# GHSA-69x3-g4r3-p962 / CVE-2026-25793: Nebula ECDSA Signature Malleability
|
||||
# Severity: HIGH (CVSS 8.1)
|
||||
# Package: github.com/slackhq/nebula v1.9.7 (embedded in /usr/bin/caddy)
|
||||
# Status: Cannot upgrade — smallstep/certificates v0.30.0-rc2 still pins nebula v1.9.x
|
||||
#
|
||||
# Vulnerability Details:
|
||||
# - ECDSA signature malleability allows bypassing certificate blocklists
|
||||
# - Attacker can forge alternate valid P256 ECDSA signatures for revoked
|
||||
# certificates (CVSSv3: AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N)
|
||||
# - Only affects configurations using Nebula-based certificate authorities
|
||||
# (non-default and uncommon in Charon deployments)
|
||||
#
|
||||
# Root Cause (Compile-Time Dependency Lock):
|
||||
# - Caddy is built with caddy-security plugin, which transitively requires
|
||||
# github.com/smallstep/certificates. That package pins nebula v1.9.x.
|
||||
# - Checked: smallstep/certificates v0.27.5 → v0.30.0-rc2 all require nebula v1.9.4–v1.9.7.
|
||||
# The nebula v1.10 API removal breaks compilation in the
|
||||
# authority/provisioner package; xcaddy build fails with upgrade attempted.
|
||||
# - Dockerfile caddy-builder stage pins nebula@v1.9.7 (Renovate tracked) with
|
||||
# an inline comment explaining the constraint (Dockerfile line 247).
|
||||
# - Fix path: once smallstep/certificates releases a version requiring
|
||||
# nebula v1.10+, remove the pin and this suppression simultaneously.
|
||||
#
|
||||
# Risk Assessment: ACCEPTED (Low exploitability in Charon context)
|
||||
# - Charon uses standard ACME/Let's Encrypt TLS; Nebula VPN PKI is not
|
||||
# enabled by default and rarely configured in Charon deployments.
|
||||
# - Exploiting this requires a valid certificate sharing the same issuer as
|
||||
# a revoked one — an uncommon and targeted attack scenario.
|
||||
# - Container-level isolation reduces the attack surface further.
|
||||
#
|
||||
# Mitigation (active while suppression is in effect):
|
||||
# - Monitor smallstep/certificates releases at https://github.com/smallstep/certificates/releases
|
||||
# - Weekly CI security rebuild flags any new CVEs in the full image.
|
||||
# - Renovate annotation in Dockerfile (datasource=go depName=github.com/slackhq/nebula)
|
||||
# will surface the pin for review when xcaddy build becomes compatible.

|
||||
# Review:
|
||||
# - Reviewed 2026-02-19: smallstep/certificates latest stable remains v0.27.5;
|

# no release requiring nebula v1.10+ has shipped. Suppression extended 14 days.
|

# - Reviewed 2026-03-13: smallstep/certificates stable still v0.27.5, extended 30 days.
|

# - Next review: 2026-04-12. Remove suppression immediately once upstream fixes.
|
||||
#
|
||||
# Removal Criteria:
|
||||
# - smallstep/certificates releases a stable version requiring nebula v1.10+
|
||||
# - Update Dockerfile caddy-builder patch to use the new versions
|

# - Rebuild image, run security scan, confirm suppression no longer needed

|

#
|

# Vulnerability Details:
|
||||
# - gRPC-Go server path-based authorization (grpc/authz) fails to match deny rules when
|
||||
# the HTTP/2 :path pseudo-header is missing its leading slash (e.g., "Service/Method"

# instead of "/Service/Method"), allowing a fallback allow-rule to grant access instead.

# - CVSSv3: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
|

#
|

# Root Cause (Third-Party Binary):
|
||||
# - Charon's own grpc dependency is patched to v1.79.3 (updated 2026-03-19).
|
||||
# - CrowdSec ships grpc v1.74.2 compiled into its binary; Charon has no control over this.
|
||||
# - This is a server-side vulnerability. CrowdSec uses grpc as a server; Charon uses it
|
||||
# only as a client (via the Docker SDK). CrowdSec's internal grpc server is not exposed
|
||||
# to external traffic in a standard Charon deployment.
|
||||
# - Fix path: once CrowdSec releases a version built with grpc >= v1.79.3, rebuild the
|
||||
# Docker image (Renovate tracks the CrowdSec version) and remove this suppression.
|
||||
#
|
||||
# Risk Assessment: ACCEPTED (Constrained exploitability in Charon context)
|
||||
# - The vulnerable code path requires an attacker to reach CrowdSec's internal grpc server,
|
||||
# which is bound to localhost/internal interfaces in the Charon container network.
|
||||
# - Container-level isolation (no exposed grpc port) significantly limits exposure.
|
||||
# - Charon does not configure grpc/authz deny rules on CrowdSec's server.

### [CRITICAL] CVE-2025-68121 · Go Stdlib Critical in CrowdSec Bundled Binaries
|
||||

| Field | Value |
|
||||
|--------------|-------|
|
||||
| **ID** | CVE-2025-68121 (see also CHARON-2025-001) |
|
||||
| **Severity** | Critical |
|
||||
| **Status** | Awaiting Upstream |
|
||||
|
||||
**What**
|
||||
A critical Go standard library vulnerability affects CrowdSec binaries bundled in the Charon
|
||||
container image. The binaries were compiled against Go 1.25.6, which contains this flaw.
|
||||
Charon's own application code, compiled with Go 1.26.1, is unaffected.
|
||||
|
||||
**Who**
|
||||
|
||||
- Discovered by: Automated scan (Grype)
|
||||
- Reported: 2026-03-20
|
||||
- Affects: CrowdSec Agent component within the container; not directly exposed through Charon's
|
||||
primary application interface
|
||||
|
||||
**Where**
|
||||
|
||||
- Component: CrowdSec Agent (bundled `cscli` and `crowdsec` binaries)
|
||||
- Versions affected: Charon container images with CrowdSec binaries compiled against Go < 1.25.7
|
||||
|
||||
**When**
|
||||
|
||||
- Discovered: 2026-03-20
|
||||
- Disclosed (if public): Not yet publicly disclosed
|
||||
- Target fix: When `golang:1.26.2-alpine` is published on Docker Hub
|
||||
|
||||
**How**
|
||||
The vulnerability resides entirely within CrowdSec's compiled binary artifacts. Exploitation
|
||||
is limited to the CrowdSec agent's internal execution paths, which are not externally exposed
|
||||
through Charon's API or network interface.
|
||||
|
||||
**Planned Remediation**
|
||||
`golang:1.26.2-alpine` is not yet available on Docker Hub. The `GO_VERSION` ARG has been
|
||||
reverted to `1.26.1` (the latest published image) until `1.26.2` is released. Once
|
||||
`golang:1.26.2-alpine` is available, bumping `GO_VERSION` to `1.26.2` and rebuilding the image
|
||||
will also resolve CVE-2026-25679 (High) and CVE-2025-61732 (High) tracked under CHARON-2025-001.

### [MEDIUM] CVE-2025-60876 · BusyBox wget HTTP Request Smuggling
|

|
||||
| **ID** | CVE-2025-60876 |
|
||||
| **Severity** | Medium · 6.5 |
|
||||
| **Status** | Awaiting Upstream |
|
||||
|
||||
**What**
|
||||
BusyBox wget through 1.37 accepts raw CR/LF and other C0 control bytes in the HTTP
|
||||
request-target, allowing request line splitting and header injection (CWE-284).
|
||||
|
||||
**Who**
|
||||
|
||||
- Discovered by: Automated scan (Grype)
|
||||
- Reported: 2026-03-24
|
||||
- Affects: Container runtime environment; Charon does not invoke busybox wget in application logic
|
||||
|
||||
**Where**
|
||||
|
||||
- Component: Alpine 3.23.3 base image (`busybox` 1.37.0-r30)
|
||||
- Versions affected: All Charon images using Alpine 3.23.3 with busybox < patched version
|
||||
|
||||
**When**
|
||||
|
||||
- Discovered: 2026-03-24
|
||||
- Disclosed (if public): Not yet publicly disclosed with fix
|
||||
- Target fix: When Alpine Security publishes a patched busybox APK
|
||||
|
||||
**How**
|
||||
The vulnerable wget applet would need to be manually invoked inside the container with
|
||||
attacker-controlled URLs. Charon's application logic does not use busybox wget. EPSS score is
|
||||
0.00064 (0.20 percentile), indicating extremely low exploitation probability.
|
||||
|
||||
**Planned Remediation**
|
||||
Monitor Alpine 3.23 for a patched busybox APK. No immediate action required. Practical risk to
|
||||
Charon users is negligible since the vulnerable code path is not exercised.

|
||||
| **Severity** | Low · 1.7 |
|
||||
| **Status** | Awaiting Upstream |
|
||||
|
||||
**What**
|
||||
`filippo.io/edwards25519` v1.1.0 `MultiScalarMult` produces invalid results or undefined
|
||||
behavior if the receiver is not the identity point. Fix available at v1.1.1 but requires
|
||||
CrowdSec to rebuild.
|
||||
|
||||
**Who**
|
||||
|
||||
- Discovered by: Automated scan (Grype)
|
||||
- Reported: 2026-03-24
|
||||
- Affects: CrowdSec Agent component within the container; not directly exposed through Charon's
|
||||
primary application interface
|
||||
|
||||
**Where**
|
||||
|
||||
- Component: CrowdSec Agent (bundled `cscli` and `crowdsec` binaries)
|
||||
- Versions affected: CrowdSec builds using `filippo.io/edwards25519` < v1.1.1
|
||||
|
||||
**When**
|
||||
|
||||
- Discovered: 2026-03-24
|
||||
- Disclosed (if public): Public
|
||||
- Target fix: When CrowdSec releases a build with updated dependency
|
||||
|
||||
**How**
|
||||
This is a rarely used advanced API within the edwards25519 library. CrowdSec does not directly
|
||||
expose MultiScalarMult to external input. EPSS score is 0.00018 (0.04 percentile).
|
||||
|
||||
**Planned Remediation**
|
||||
Awaiting CrowdSec upstream release with updated dependency. No action available for Charon
|
||||
maintainers.

### ✅ [CRITICAL] CVE-2025-68121 · Go Stdlib Critical in CrowdSec Bundled Binaries
|
||||
|
||||
| Field | Value |
|
||||
|--------------|-------|
|
||||
| **ID** | CVE-2025-68121 (see also CHARON-2025-001) |
|
||||
| **Severity** | Critical |
|
||||
| **Patched** | 2026-03-24 |
|
||||
|
||||
**What**
|
||||
A critical Go standard library vulnerability affects CrowdSec binaries bundled in the Charon
|
||||
container image. The binaries were compiled against Go 1.25.6, which contains this flaw.
|
||||
Charon's own application code, compiled with Go 1.26.1, is unaffected.

**Where**
|
||||
|

||||
- Patched: 2026-03-24
|
||||
- Time to patch: 4 days
|
||||
|
||||
**How**
|
||||
The vulnerability resides entirely within CrowdSec's compiled binary artifacts. Exploitation
|
||||
is limited to the CrowdSec agent's internal execution paths, which are not externally exposed
|
||||
through Charon's API or network interface.
|
||||
|
||||
**Resolution**
|

# QA Security Audit Report — CWE-614 Remediation
|
||||
|
||||
**Date:** 2026-03-21
|
||||
**Scope:** `backend/internal/api/handlers/auth_handler.go` — removal of `secure = false` branch from `setSecureCookie`
|
||||
**Audited by:** QA Security Agent
|
||||
|
||||
---
|
||||
|
||||
## Scope
|
||||
|
||||
Backend-only change. File audited:
|
||||
|
||||
| File | Change Type |
|
||||
|------|-------------|
|
||||
| `backend/internal/api/handlers/auth_handler.go` | Modified — `secure = false` branch removed; `Secure` always `true` |
|
||||
| `backend/internal/api/handlers/auth_handler_test.go` | Modified — all `TestSetSecureCookie_*` assertions updated to `assert.True(t, cookie.Secure)` |
|
||||
|
||||
---
|
||||
|
||||
## 1. Test Results
|
||||
|
||||
| Metric | Value | Gate | Status |
|
||||
|---|---|---|---|
|
||||
| Statement coverage | 88.0% | ≥ 87% | ✅ PASS |
|
||||
| Line coverage | 88.2% | ≥ 87% | ✅ PASS |
|
||||
| Test failures | 0 | 0 | ✅ PASS |
|
||||
|
||||
All `TestSetSecureCookie_*` variants assert `cookie.Secure == true` unconditionally, correctly reflecting the remediated behaviour.
|
||||
|
||||
---
|
||||
|
||||
## 2. Lint Results
|
||||
|
||||
**Tool:** `golangci-lint` (fast config — staticcheck, govet, errcheck, ineffassign, unused)
|
||||
|
||||
**Result:** `0 issues` — ✅ PASS
|
||||
|
||||
---
|
||||
|
||||
## 3. Pre-commit Hooks
|
||||
|
||||
**Tool:** Lefthook v2.1.4
|
||||
|
||||
| Hook | Result |
|
||||
|---|---|
|
||||
| check-yaml | ✅ PASS |
|
||||
| actionlint | ✅ PASS |
|
||||
| end-of-file-fixer | ✅ PASS |
|
||||
| trailing-whitespace | ✅ PASS |
|
||||
| dockerfile-check | ✅ PASS |
|
||||
| shellcheck | ✅ PASS |
|
||||
|
||||
Go-specific hooks (`go-vet`, `golangci-lint-fast`) were skipped — no staged files. These were validated directly via `make lint-fast`.

|
||||
|
||||
## 4. Trivy Security Scan
|
||||
|
||||
**Tool:** Trivy v0.52.2
|
||||
|
||||
### New Vulnerabilities Introduced by This Change
|
||||
|
||||
**None.** Zero HIGH or CRITICAL vulnerabilities attributable to the CWE-614 remediation.
|
||||
|
||||
### Pre-existing Baseline Finding (unrelated)
|
||||
|
||||
| ID | Severity | Type | Description |
|
||||
|---|---|---|---|
|
||||
| DS002 | HIGH | Dockerfile misconfiguration | Container runs as root — pre-existing, not introduced by this change |

|
||||
|
||||
## 5. CWE-614 Verification
|
||||
|
||||
### Pattern Search: `secure = false` in handlers package
|
||||
|
||||
```
|
||||
grep -rn "secure = false" /projects/Charon/backend/
|
||||
```
|
||||
|
||||
**Result:** 0 matches — ✅ CLEARED
|
||||
|
||||
### Pattern Search: Inline CodeQL suppression
|
||||
|
||||
```
|
||||
grep -rn "codeql[go/cookie-secure-not-set]" /projects/Charon/backend/
|
||||
```
|
||||
|
||||
**Result:** 0 matches — ✅ CLEARED
|
||||
|
||||
### `setSecureCookie` Implementation
|
||||
|
||||
The function unconditionally passes `true` as the `secure` argument to `c.SetCookie`:
|
||||
|
||||
```go
|
||||
c.SetCookie(
|
||||
name, // name
|
||||
value, // value
|
||||
maxAge, // maxAge in seconds
|
||||
"/", // path
|
||||
domain, // domain (empty = current host)
|
||||
true, // secure ← always true, no conditional branch
|
||||
true, // httpOnly
|
||||
)
|
||||
```
|
||||
|
||||
All test cases (`TestSetSecureCookie_HTTPS_Strict`, `_HTTP_Lax`, `_HTTP_Loopback_Insecure`,
|
||||
`_ForwardedHTTPS_*`, `_HTTP_PrivateIP_Insecure`, `_HTTP_10Network_Insecure`,
|
||||
`_HTTP_172Network_Insecure`) assert `cookie.Secure == true`.
|
||||
|
||||
---
|
||||
|
||||
## Summary
|
||||
|
||||
| Check | Result | Notes |
|
||||
|---|---|---|
|
||||
| Backend unit tests | ✅ PASS | 0 failures, 88.0% coverage (gate: 87%) |
|
||||
| Lint | ✅ PASS | 0 issues |
|
||||
| Pre-commit hooks | ✅ PASS | All 6 active hooks passed |
|
||||
| Trivy | ✅ PASS | No new HIGH/CRITICAL vulns |
|
||||
| `secure = false` removed | ✅ CLEARED | 0 matches in handlers package |
|
||||
| CodeQL suppression removed | ✅ CLEARED | 0 matches in handlers package |
|
||||
|
||||
---
|
||||
|
||||
## Overall: ✅ PASS
|
||||
|
||||
The CWE-614 remediation is complete and correct. All cookies set by `setSecureCookie` now unconditionally carry `Secure = true`. No regressions, no new security findings, and coverage remains above the required threshold.

## Security Focus Area Results
|
||||
|
||||
### 1. Credential Handling — `TMP_COOKIE`
|
||||
|
||||
**`mktemp` usage**: `TMP_COOKIE=$(mktemp)` at line 208. Creates a file in `/tmp` with `600` permissions via the OS. ✅ SECURE.
|
||||
|
||||
**Removal on exit**: The `cleanup()` function at line 103 removes the file with `rm -f "${TMP_COOKIE:-}"`. However, `cleanup` is only registered via explicit calls — there is **no `trap cleanup EXIT`**. Only `trap on_failure ERR` is registered (line 108).
|
||||
|
||||
**Gap**: On 5 early `exit 1` paths after line 208 (login failure L220, auth failure L251, Caddy readiness failure L282, security config failure L299, and handler verification failure L316), `cleanup` is never called. The cookie file is left in `/tmp`.
|
||||
|
||||
**Severity**: LOW — The cookie contains session credentials for a localhost test server (`ratelimit@example.local` / `password123`, non-production). CI runners are ephemeral and auto-cleaned. Local runs will leave a `/tmp/tmp.XXXXXX` file until next reboot or manual cleanup.
|
||||
|
||||
**Note**: The exit at line 386 (inside the 429 enforcement failure block) intentionally skips cleanup to leave containers running for manual inspection. This is by design and acceptable.
|
||||
|
||||
**Recommendation**: Add `trap cleanup EXIT` immediately after `trap on_failure ERR` (line 109) to ensure the cookie file is always removed.
|
||||
|
||||
---
|
||||
|
||||
### 2. `curl` — Sensitive Values in Command-Line Arguments
|
||||
|
||||
Cookie file path is passed via `-c ${TMP_COOKIE}` and `-b ${TMP_COOKIE}` (unquoted). No credentials, tokens, or API keys are passed as command-line arguments. All authentication is via the cookie file (read/write by path), which is the correct pattern — cookie values never appear in `ps` output.
|
||||
|
||||
**Finding (LOW)**: `${TMP_COOKIE}` is unquoted in all 6 curl invocations. `mktemp` on Linux produces paths of the form `/tmp/tmp.XXXXXX` which never contain spaces or shell metacharacters under default `$TMPDIR`. However, under a non-standard `$TMPDIR` (e.g., `/tmp/my dir/`) this would break. This is a portability issue, not a security issue.
|
||||
|
||||
**Recommendation**: Quote `"${TMP_COOKIE}"` in all curl invocations.
|
||||
|
||||
---
|
||||
|
||||
### 3. Shell Injection
|
||||
|
||||
All interpolated values in curl `-d` payloads are either:
|
||||
- Script-level constants (`RATE_LIMIT_REQUESTS=3`, `RATE_LIMIT_WINDOW_SEC=10`, `RATE_LIMIT_BURST=1`, `TEST_DOMAIN=ratelimit.local`, `BACKEND_CONTAINER=ratelimit-backend`)
|
||||
- Values derived from API responses stored in double-quoted variables (`"$CREATE_RESP"`, `"$SEC_CONFIG_RESP"`)
|
||||
|
||||
No shell injection vector exists. All heredoc expansions (`cat <<EOF...EOF`) expand only the hardcoded constants listed above.
|
||||
|
||||
The UUID extraction pattern at line 429 includes `${TEST_DOMAIN}` unquoted within a `grep -o` pattern, but because the variable expands to `ratelimit.local` (controlled constant), this has no injection risk. The `.` in `ratelimit.local` is treated as a regex wildcard but in this context only matches the intended hostname. ✅ PASS.
|
||||
|
||||
---
|
||||
|
||||
### 4. `set -euo pipefail` Compatibility
|
||||
|
||||
The new status-capture idiom:
|
||||
|
||||
```bash
|
||||
LOGIN_STATUS=$(curl -s -w "\n%{http_code}" ... | tail -n1)
|
||||
```
|
||||
|
||||
Behavior under `set -euo pipefail`:
|
||||
- **Network failure** (curl exits non-zero, e.g., `ECONNREFUSED`): `pipefail` propagates curl's non-zero exit through the pipeline; the assignment fails; `set -e` fires the `on_failure` ERR trap and exits. ✅ Correct.
|
||||
- **HTTP error** (curl exits 0, HTTP 4xx/5xx): curl outputs `\n{code}`; `tail -n1` extracts the code; assignment succeeds; subsequent `[ "$LOGIN_STATUS" != "200" ]` detects the failure. ✅ Correct.
|
||||
- **Empty body edge case**: If curl returns an empty body, output is `\n200`. `tail -n1` → `200`; `head -n-1` → empty string. Status check still works. ✅ Correct.
|
||||
|
||||
The `SEC_CONFIG_RESP` split pattern (`tail -n1` for status, `head -n-1` for body) is correct for both single-line and multiline JSON responses. ✅ PASS.
|
||||
|
||||
---
|
||||
|
||||
### 5. Workflow Secrets Exposure
|
||||
|
||||
The workflow (`rate-limit-integration.yml`) contains **no `${{ secrets.* }}` references**. All test credentials are hardcoded constants in the script (`ratelimit@example.local` / `password123`), appropriate for an ephemeral test user that is registered and used only within the test run.
|
||||
|
||||
`$GITHUB_STEP_SUMMARY` output includes: container status, API config JSON, container logs. None of these contain secrets or credentials. The security config JSON may contain rate limit settings (integers) but nothing sensitive.
|
||||
|
||||
No accidental log exposure identified. ✅ PASS.
|
||||
|
||||
---
|
||||
|
||||
### 6. GeoIP Change — Supply-Chain Risk
|
||||
|
||||
**Change**: The non-CI Dockerfile build path previously ran `sha256sum -c -` against `GEOLITE2_COUNTRY_SHA256`. This was removed. The remaining guard is `[ -s /app/data/geoip/GeoLite2-Country.mmdb ]` (file-size non-empty check).
|
||||
|
||||
**Risk assessment** (MEDIUM): The download source is `https://github.com/P3TERX/GeoLite.mmdb/raw/download/GeoLite2-Country.mmdb`, a public GitHub repository. If this repository is compromised or the file is replaced with a malicious binary:
|
||||
- The `-s` check only verifies the file is non-empty
|
||||
- The application loads it at `CHARON_GEOIP_DB_PATH` for IP geolocation — a non-privileged read operation
|
||||
- A malicious file would not achieve RCE via MMDb parsing in the MaxMind reader library (no known attack surface), but could corrupt GeoIP lookups silently
|
||||
|
||||
**This is an acknowledged, pre-existing architectural limitation** documented in the spec. The `sha256sum` check was ineffective by design because the P3TERX repository updates the file continuously while the pinned hash only updates weekly via `update-geolite2.yml`. The new behavior (accept any non-empty file) is more honest about the actual constraint.
|
||||
|
||||
**Spec compliance**: `ARG GEOLITE2_COUNTRY_SHA256` is **retained** in the Dockerfile (line ~441) as required by the spec, preserving `update-geolite2.yml` workflow compatibility. ✅ PASS.
|
||||
|
||||
**Residual risk**: MEDIUM. Mitigated by: (1) `wget` uses HTTPS to fetch from GitHub (TLS in transit), (2) downstream Trivy scans of the built image would flag a malicious MMDB independently, (3) the GeoIP reader is sandboxed to a read operation with no known parse-exploit surface.

## Correctness Against Spec
|
||||
|
||||
| Spec Change | Implemented | Verified |
|
||||
|-------------|-------------|----------|
|
||||
| C1: Login status check (Step 4) | ✅ Yes — `LOGIN_STATUS` checked, fails fast on non-200 | Script lines 211–220 |
|
||||
| C2: Proxy host creation — auth failures fatal, 409 continues | ✅ Yes — 401/403 abort, other non-201 continues | Script lines 248–256 |
|
||||
| C3: Caddy admin API readiness gate before security config POST | ✅ Yes — 20-retry loop before SEC_CFG call | Script lines 274–284 |
|
||||
| C4: Security config POST status checked | ✅ Yes — `SEC_CONFIG_STATUS` checked, body logged on error | Script lines 286–301 |
|
||||
| C5: `verify_rate_limit_config` failure is hard exit | ✅ Yes — prints debug and `exit 1` | Script lines 307–318 |
|
||||
| C6: Pre-verification sleep increased 5 → 8 s | ✅ Yes — `sleep 8` | Script line 305 |
|
||||
| C7: Trailing slash on `/config/` | ✅ Yes — all 6 script occurrences; workflow line 71 | Confirmed by grep |
|
||||
| Dockerfile: sha256sum removed from non-CI path | ✅ Yes — only `-s` check remains | Dockerfile lines ~453–463 |
|
||||
| Dockerfile: `ARG GEOLITE2_COUNTRY_SHA256` retained | ✅ Yes — line ~441 | Dockerfile audited |

## Findings Summary
|
||||
|
||||
| ID | Severity | Area | Description |
|
||||
|----|----------|------|-------------|
|
||||
| M1 | MEDIUM | Dockerfile supply-chain | GeoIP downloaded without hash; `-s` is minimum viability only. Accepted trade-off per spec — hash was perpetually stale. |
|
||||
| L1 | LOW | Shell security | `${TMP_COOKIE}` unquoted in 6 curl invocations. No practical impact under standard `$TMPDIR`. |
|
||||
| L2 | LOW | Temp file hygiene | No `trap cleanup EXIT`; TMP_COOKIE and containers not cleaned on 5 early failure paths (lines 220, 251, 282, 299, 316). Low sensitivity (localhost test credentials only). |
|
||||
|
||||
No CRITICAL or HIGH severity findings.
|
||||
|
||||
---
|
||||
|
||||
## Overall Verdict
|
||||
|
||||
**✅ APPROVED**
|
||||
|
||||
All spec-required changes are correctly implemented. No OWASP Top 10 vulnerabilities were introduced. The two LOW findings (unquoted variable, missing EXIT trap) are hygiene improvements that do not block the fix. The MEDIUM GeoIP supply-chain concern is a pre-existing architectural trade-off explicitly acknowledged in the spec.
|
||||
|
||||
### Recommended follow-up (non-blocking)
|
||||
|
||||
Add `trap cleanup EXIT` immediately after `trap on_failure ERR` in `scripts/rate_limit_integration.sh` to ensure TMP_COOKIE is always removed and containers are cleaned on all exit paths.
|
||||
**Purpose:** Allow admins to set a setting to an empty string value (required to fix the fresh-install CrowdSec enabling bug where `value` was legitimately empty).
|
||||
|
||||
---
|
||||
|
||||
## Overall Verdict: APPROVED
|
||||
|
||||
All structural, linting, and security gates pass. The change is correctly scoped to the build-only `frontend-builder` stage and introduces no new attack surface in the final runtime image.

## 1. Dockerfile Structural Verification
|
||||
|
||||
### Global ARG block (lines 25–40)
|
||||
|
||||
```
|
||||
29: # renovate: datasource=npm depName=npm
|
||||
30: ARG NPM_VERSION=11.11.1
|
||||
```
|
||||
|
||||
Both the Renovate comment and the pinned ARG are present in the correct order. Renovate will track `npm` releases on `datasource=npm` and propose version bumps automatically.
|
||||
|
||||
### frontend-builder stage (lines 93–115)
|
||||
|
||||
```
|
||||
93: FROM --platform=$BUILDPLATFORM node:24.14.0-alpine@sha256:... AS frontend-builder
|
||||
...
|
||||
105: ARG NPM_VERSION
|
||||
106: # hadolint ignore=DL3017
|
||||
107: RUN apk upgrade --no-cache && \
|
||||
108: npm install -g npm@${NPM_VERSION} --no-fund --no-audit && \

||||
109: npm cache clean --force
|
||||
...
|
||||
111: RUN npm ci
|
||||
```
|
||||
|
||||
All structural requirements confirmed: bare re-declaration, lint suppression on dedicated line, three-command RUN, and unmodified `npm ci`.

|
||||
|
||||
## 3. Logical Security Review
|
||||
|
||||
### Attack surface — build-only stage
|
||||
|
||||
The `frontend-builder` stage is strictly a build artifact producer. The final runtime image receives only compiled frontend assets via a single targeted `COPY`:
|
||||
|
||||
```
|
||||
COPY --from=frontend-builder /app/frontend/dist /app/frontend/dist
|
||||
```
|
||||
|
||||
The Alpine OS packages upgraded by `apk upgrade --no-cache`, the globally installed npm binary, and all `node_modules` are confined to the builder layer and never reach the runtime image. The CVE remediation has zero footprint in the deployed container.
|
||||
|
||||
### `--no-audit` flag
|
||||
|
||||
`--no-audit` suppresses npm audit output during `npm install -g npm@${NPM_VERSION}`. This applies only to the single-package global npm tool upgrade, not to the project dependency installation. `npm ci` on line 111 installs project dependencies from `package-lock.json` and is unaffected by this flag. Suppressing audit during a build-time tool upgrade is the standard pattern for avoiding advisory database noise that cannot be acted on during the image build.
|
||||
|
||||
### `npm cache clean --force`
|
||||
|
||||
Clears the npm package cache between the global npm upgrade and the `npm ci` run. This is safe: it ensures the freshly installed npm binary is used without stale cache entries left by the older npm version bundled in the base image. The `--force` flag suppresses npm's deprecation warning about manual cache cleaning; it does not alter the clean operation itself.

# Supply Chain Security Scan Report — CVE Investigation

| Field | Value |
|

|-------------|--------------------------------|
|
||||
| **Date** | 2026-03-24 |
|

|
||||
|
||||
## Executive Summary
|
||||
|
||||
The CVEs flagged for `goxmldsig`, `buger/jsonparser`, and `jackc/pgproto3/v2` are **false positives for the Charon project**. These packages are not in Charon's Go module dependency graph. They originate from Go build info embedded in third-party compiled binaries shipped inside the Docker image — specifically the CrowdSec and Caddy binaries.
|
||||
The current `charon:local` image built on 2026-03-24 shows a significantly improved
|
||||
security posture compared to the CI baseline. Three previously tracked SECURITY.md
|
||||
vulnerabilities are now **resolved** due to Go 1.26.1 compilation and Alpine package
|
||||
updates. Two new medium/low findings emerged. No CRITICAL or HIGH active
|
||||
vulnerabilities remain in the unignored scan results.
|
||||
|
||||
`CVE-2026-33186` (`google.golang.org/grpc`) is **resolved in Charon's own source code** (bumped to v1.79.3), but the same CVE still appears in the SBOM because older grpc versions are embedded in the CrowdSec (`v1.74.2`) and Caddy (`v1.79.1`) binaries in the Docker image. Those are out-of-scope for Charon to patch directly.
|
||||
|
||||
The most actionable findings are stale compiled Charon binaries built with go1.25.4–go1.25.6 that carry Critical/High stdlib CVEs and should be rebuilt with the current go1.26.1 toolchain.
|
||||

## 1. Root Cause: Why These Packages Appear in Scans
|
||||
## Scans Executed
|
||||
|
||||
### Mechanism: go-module-binary-cataloger
|
||||
|
||||
When Syft generates the SBOM from the Docker image (not from source), it uses the **`go-module-binary-cataloger`** to read embedded Go build info from all compiled Go binaries in the image. Every Go binary compiled since Go 1.18 embeds a complete list of its upstream module dependencies via `debug/buildinfo`.
|
||||
|
||||
This means Syft finds packages from *any* Go binary on the image filesystem — including third-party tools like CrowdSec and Caddy — and reports them as if they were Charon dependencies.
|
||||
|
||||
### Confirmed Binary Sources
|
||||
|
||||
| Package | Version | Binary Path | Binary's Main Module |
|
||||
|---|---|---|---|
|
||||
| `github.com/buger/jsonparser` | v1.1.1 | `/usr/local/bin/crowdsec`, `/usr/local/bin/cscli` | `github.com/crowdsecurity/crowdsec` |
|
||||
| `github.com/jackc/pgproto3/v2` | v2.3.3 | `/usr/local/bin/crowdsec`, `/usr/local/bin/cscli` | `github.com/crowdsecurity/crowdsec` |
|
||||
| `github.com/russellhaering/goxmldsig` | v1.5.0 | `/usr/bin/caddy` | `caddy` |
|
||||
| `google.golang.org/grpc` | v1.74.2 | `/usr/local/bin/crowdsec`, `/usr/local/bin/cscli` | `github.com/crowdsecurity/crowdsec` |
|
||||
| `google.golang.org/grpc` | v1.79.1 | `/usr/bin/caddy` | `caddy` |
|
||||
|
||||
**Verification**: None of these packages appear in `backend/go.mod`, `backend/go.sum`, or the output of `go mod graph`.
|
||||
|
||||
### Why `grype dir:.` Flags Module Cache Artifacts
|
||||
|
||||
Running `grype dir:.` over the Charon workspace also scans `.cache/go/pkg/mod/` — the local Go module download cache. This directory contains the `go.mod` files of every transitively downloaded module. Grype reads those `go.mod` files and flags vulnerable version references within them, even though those versions are not compiled into the Charon binary. All module-cache findings have locations beginning with `/.cache/go/pkg/mod/` and are not exploitable in Charon.
|
||||
|
||||
### Stale SBOM: `sbom-generated.json`
|
||||
|
||||
`sbom-generated.json` (dated **2026-02-21**) was generated by an earlier workflow before the grpc bump and uses a format with no version or PURL data. Grype reading this file matches vulnerabilities against package names alone with no version filter, inflating findings. The authoritative SBOM is `sbom.cyclonedx.json` (dated **2026-03-18**, generated by Syft 1.42.2).

| **CrowdSec binary (`/usr/local/bin/crowdsec`)** | v1.74.2 — out of scope |
|
||||
| **Caddy binary (`/usr/bin/caddy`)** | v1.79.1 — out of scope |
|
||||
| **False positive for Charon?** | Partially — Charon's own code is patched. SBOM findings persist from Docker image binaries. |

| **Severity** | Medium (CVSS 6.5) |
|

| **Package** | `busybox` 1.37.0-r30 (Alpine APK) |
|
||||
| **Affected** | `busybox`, `busybox-binsh`, `busybox-extras`, `ssl_client` (4 matches) |
|

| **Fix Available** | No |
|
||||
| **Classification** | AWAITING UPSTREAM |
|
||||
| **EPSS** | 0.00064 (0.20 percentile) |
|
||||
|
||||
**Remediation**: Upgrade the CrowdSec and Caddy Docker image versions. The fix in Charon's source is complete.
|
||||
**Description**: BusyBox wget through 1.37 accepts raw CR/LF and other C0 control bytes
|
||||
in the HTTP request-target, allowing request line splitting and header injection (CWE-284).
|
||||
|
||||
**Risk Assessment**: Low practical risk. Charon does not invoke `busybox wget` in its
|
||||
application logic. The vulnerable `wget` applet would need to be manually invoked inside
|
||||
the container with attacker-controlled URLs.
|
||||
|
||||
**Remediation**: Monitor Alpine 3.23 for a patched `busybox` APK. No action required
|
||||
until upstream ships a fix.

| **Classification** | AWAITING UPSTREAM |
|
||||
| **EPSS** | 0.00018 (0.04 percentile) |
|
||||
|
||||
**Remediation**: Requires upgrading the Caddy Docker image tag. Track upstream Caddy release notes for a patched `goxmldsig` dependency.
|
||||
**Description**: `MultiScalarMult` produces invalid results or undefined behavior if
|
||||
the receiver is not the identity point. This is a rarely used, advanced API.
|
||||
|
||||
**Risk Assessment**: Minimal. CrowdSec does not directly expose edwards25519
|
||||
`MultiScalarMult` to external input. The fix exists at v1.1.1 but requires CrowdSec
|
||||
to rebuild with the updated dependency.
|
||||
|

**Remediation**: Awaiting CrowdSec upstream release with updated dependency. No
|
||||
action available for Charon maintainers.

|
||||
TLS 1.3 server. Alpine 3.23 still ships 3.5.5-r0. Risk accepted pending Alpine patch.

## 3. Actionable Findings
|
||||
### GHSA-jqcq-xjh3-6g23 / GHSA-x6gf-mpr2-68h6 / CVE-2026-4427 — DoS in pgproto3/v2 (CrowdSec)
|
||||
|
||||
### 3.1 Stdlib CVEs in Stale Charon Binaries (Critical/High)
|
||||
| Field | Value |
|
||||
|------------------|-------|
|
||||
| **Severity** | High (CVSS 7.5) |
|
||||
| **Package** | `github.com/jackc/pgproto3/v2` v2.3.3 |
|
||||
| **Matches** | 4 (2 GHSAs × 2 binaries) |
|
||||
| **Fix Available** | No (v2 is archived/EOL) |
|
||||
| **Classification** | ALREADY DOCUMENTED · AWAITING UPSTREAM |
|
||||
|
||||
Grype found Charon binaries on-disk compiled with old Go versions. The current toolchain is **go1.26.1**, which patches all of the following.
|
||||
|
||||
| Binary | Go Version | Notable CVEs |
|
||||
|---|---|---|
|
||||
| `.trivy_logs/charon_binary` | go1.25.4 (Nov 2025 artifact) | CVE-2025-68121 (Critical), CVE-2025-61726/29/31/32 (High) |
|
||||
| `backend/bin/charon`, `backend/bin/api`, `backend/bin/charon-debug` | go1.25.6 | CVE-2025-68121 (Critical), CVE-2025-61732 (High), CVE-2026-25679 (High) |
|
||||
| `backend/api` (root-level) | go1.25.7 | CVE-2026-25679 (High), CVE-2026-27142 (Medium) |
|
||||
|
||||
**CVE-2025-68121** (Critical, Go stdlib) is the single highest-severity finding in this report.
|
||||
|
||||
**Remediation**: Rebuild all binaries with go1.26.1. Delete `.trivy_logs/charon_binary` (stale Nov 2025 artifact) or add `.trivy_logs/` to `.gitignore`.
|
||||
pgproto3/v2 is archived with no fix planned. CrowdSec must migrate to pgx/v5.
|
||||
Charon uses SQLite, not PostgreSQL; this code path is unreachable in standard
|
||||
deployment.

## 4. Scan Configuration Recommendations
|
||||
### CVE-2026-27171 — zlib CPU Exhaustion (RESOLVED)
|
||||
|
||||
### Exclude Go Module Cache from `grype dir:.`
|
||||
|
||||
Create `.grype.yaml` at project root:
|
||||
|
||||
```yaml
|
||||
ignore:
|
||||
- package:
|
||||
location: "**/.cache/**"
|
||||
- package:
|
||||
location: "**/node_modules/**"
|
||||
```
|
||||
|
||||
Alternatively, scan the SBOM directly rather than the filesystem: `grype sbom:sbom.cyclonedx.json`.
|
||||
|
||||
### Regenerate or Remove `sbom-generated.json`
|
||||
|
||||
`sbom-generated.json` (Feb 21 2026) contains packages with no version or PURL data, causing name-only vulnerability matching. Delete it or regenerate with: `syft scan dir:. -o cyclonedx-json > sbom-generated.json`.
|
||||
|
||||
### Delete or Gitignore `.trivy_logs/charon_binary`
|
||||
|
||||
The 23MB stale binary `.trivy_logs/charon_binary` (go1.25.4, Nov 2025) is a Trivy scan artifact causing several Critical/High CVE findings. Add `.trivy_logs/*.binary` or the whole `.trivy_logs/` directory to `.gitignore`.
|
||||
| Field | Value |
|
||||
|------------------|-------|
|
||||
| **Previous Severity** | Medium |
|
||||
| **Resolution** | Alpine now ships `zlib` 1.3.2-r0 (fix threshold: 1.3.2) |
|
||||
| **Verified** | Not detected in Grype scan; zlib 1.3.2-r0 confirmed in SBOM |

|------------------|-------|
|

| **Severity** | Medium (CodeQL) |
|
||||
| **File** | `backend/internal/api/handlers/auth_handler.go:152` |
|
||||
| **Classification** | FALSE POSITIVE (stale SARIF) |
|
||||
|
||||
**Finding**: CodeQL reports "Cookie does not set Secure attribute to true" at line 152.
|
||||
|
||||
**Verification**: The `setSecureCookie` function at line 148-156 calls `c.SetCookie()`
|
||||
with `secure: true` (6th positional argument). The Secure attribute IS set correctly.
|
||||
This SARIF was generated from a previous code version and does not reflect the current
|
||||
source. **The CodeQL SARIF files should be regenerated.**
|
||||
|
||||
### JavaScript / JS
|
||||
|
||||
No findings. Both `codeql-results-javascript.sarif` and `codeql-results-js.sarif` contain
|
||||
0 results.

## GORM Security Scanner
|
||||
|
||||
| Metric | Value |
|
||||
|------------|-------|
|

| **Result** | PASSED |
|
||||
| **Files** | 43 Go files (2,396 lines) |
|

| **Critical** | 0 |
|
||||
| **High** | 0 |
|
||||
| **Medium** | 0 |
|
||||
| **Info** | 2 (missing indexes on foreign keys in `UserPermittedHost`) |
|
||||
|
||||
The 2 informational suggestions (`UserID` and `ProxyHostID` missing `gorm:"index"` in
|
||||
`backend/internal/models/user.go:130-131`) are performance recommendations, not security
|
||||
issues. They do not block this audit.
|
||||
|
||||
---
|
||||
|
||||
## CI vs Local Scan Discrepancy
|
||||
|
||||
The CI reported **3 Critical, 5 High, 1 Medium**. The local scan on the freshly built
|
||||
image reports **0 Critical, 0 High, 4 Medium, 2 Low** (active) plus **4 High** (ignored).
|
||||
|
||||
**Root causes for the discrepancy:**
|
||||
|
||||
1. **Resolved vulnerabilities**: 3 Critical and 4 High findings were resolved by Go 1.26.1
|
||||
compilation and upstream Caddy/CrowdSec dependency updates since the CI image was built.
|
||||
2. **Grype ignore rules**: The local scan applies documented risk acceptance rules that
|
||||
suppress 4 High findings in third-party binaries. CI (Trivy) does not use these rules.
|
||||
3. **Stale CI artifacts**: The `trivy-image-report.json` dates from 2026-02-25 and does
|
||||
not reflect the current image state. The `codeql-results-go.sarif` references code that
|
||||
has since been fixed.
|
||||
|
||||
---
|
||||
|
||||
## Recommended Actions
|
||||
|
||||
### Immediate (This Sprint)
|
||||
|
||||
1. **Update SECURITY.md**: Move CVE-2025-68121, CHARON-2025-001, and CVE-2026-27171 to
|
||||
a "Patched Vulnerabilities" section. Add CVE-2025-60876 and CVE-2026-26958 as new
|
||||
known vulnerabilities.
|
||||
|
||||
2. **Regenerate stale scan artifacts**: Re-run Trivy image scan and CodeQL analysis to
|
||||
produce current SARIF/JSON files. The existing files predate fixes and produce
|
||||
misleading CI results.
|
||||
|
||||
3. **Clean up Grype ignore rules**: Remove ignore entries for vulnerabilities that are
|
||||
no longer detected (CVE-2026-33186, GHSA-69x3-g4r3-p962, GHSA-479m-364c-43vc).
|
||||
Stale ignore rules obscure the actual security posture.
|
||||
|
||||
### Next Release
|
||||
|
||||
4. **Monitor Alpine APK updates**: Watch for patched `busybox` (CVE-2025-60876) and
|
||||
`openssl` (CVE-2026-2673) packages in Alpine 3.23.
|
||||
|
||||
5. **Monitor CrowdSec releases**: Watch for CrowdSec builds with updated
|
||||
`filippo.io/edwards25519` >= v1.1.1, `buger/jsonparser` >= v1.1.2, and
|
||||
`pgx/v5` migration (replacing pgproto3/v2).
|
||||
|
||||
6. **Monitor Go 1.26.2-alpine**: When available, bump `GO_VERSION` to pick up any
|
||||
remaining stdlib patches.
|
||||
|
||||
### Informational (Non-Blocking)
|
||||
|
||||
7. **GORM indexes**: Consider adding `gorm:"index"` to `UserID` and `ProxyHostID` in
|
||||
`UserPermittedHost` for query performance.
|
||||
|
||||
---
|
||||
|
||||
## Gotify Token Review
|
||||
|
||||
Verified: No Gotify application tokens appear in scan output, log artifacts, test results,
|
||||
API examples, or URL query parameters. All diagnostic output is clean.
|
||||
|
||||
---
|
||||
|
||||
## Conclusion
|
||||
|
||||
The Charon container image security posture has materially improved. Six previously known
|
||||
vulnerabilities are now resolved through Go toolchain and dependency updates. The remaining
|
||||
active findings are medium/low severity, reside in Alpine base packages and CrowdSec
|
||||
third-party binaries, and have no available fixes. No vulnerabilities exist in Charon's
|
||||
own application code. GORM and CodeQL scans confirm the backend code is clean.

# QA Security Audit Report — CWE-614 Remediation
|
||||
|
||||
**Date:** 2026-03-21
|
||||
**Scope:** `backend/internal/api/handlers/auth_handler.go` — removal of `secure = false` branch from `setSecureCookie`
|
||||
**Audited by:** QA Security Agent
|
||||
|
||||
---
|
||||
|
||||
## Scope
|
||||
|
||||
Backend-only change. File audited:
|
||||
|
||||
| File | Change Type |
|
||||
|------|-------------|
|
||||
| `backend/internal/api/handlers/auth_handler.go` | Modified — `secure = false` branch removed; `Secure` always `true` |
|
||||
| `backend/internal/api/handlers/auth_handler_test.go` | Modified — all `TestSetSecureCookie_*` assertions updated to `assert.True(t, cookie.Secure)` |
|
||||
|
||||
---
|
||||
|
||||
## 1. Test Results
|
||||
|
||||
| Metric | Value | Gate | Status |
|
||||
|---|---|---|---|
|
||||
| Statement coverage | 88.0% | ≥ 87% | ✅ PASS |
|
||||
| Line coverage | 88.2% | ≥ 87% | ✅ PASS |
|
||||
| Test failures | 0 | 0 | ✅ PASS |
|
||||
|
||||
All `TestSetSecureCookie_*` variants assert `cookie.Secure == true` unconditionally, correctly reflecting the remediated behaviour.
|
||||
|
||||
---
|
||||
|
||||
## 2. Lint Results
|
||||
|
||||
**Tool:** `golangci-lint` (fast config — staticcheck, govet, errcheck, ineffassign, unused)
|
||||
|
||||
**Result:** `0 issues` — ✅ PASS
|
||||
|
||||
---
|
||||
|
||||
## 3. Pre-commit Hooks
|
||||
|
||||
**Tool:** Lefthook v2.1.4
|
||||
|
||||
| Hook | Result |
|
||||
|---|---|
|
||||
| check-yaml | ✅ PASS |
|
||||
| actionlint | ✅ PASS |
|
||||
| end-of-file-fixer | ✅ PASS |
|
||||
| trailing-whitespace | ✅ PASS |
|
||||
| dockerfile-check | ✅ PASS |
|
||||
| shellcheck | ✅ PASS |
|
||||
|
||||
Go-specific hooks (`go-vet`, `golangci-lint-fast`) were skipped — no staged files. These were validated directly via `make lint-fast`.
|
||||
|

|
||||
|
||||
## 4. Trivy Security Scan
|
||||
|
||||
**Tool:** Trivy v0.52.2
|
||||
|
||||
### New Vulnerabilities Introduced by This Change
|
||||
|
||||
**None.** Zero HIGH or CRITICAL vulnerabilities attributable to the CWE-614 remediation.
|
||||
|
||||
### Pre-existing Baseline Finding (unrelated)
|
||||
|
||||
| ID | Severity | Type | Description |
|
||||
|---|---|---|---|
|
||||
| DS002 | HIGH | Dockerfile misconfiguration | Container runs as root — pre-existing, not introduced by this change |
|
||||
|
||||
---
|
||||
|
||||
## 5. CWE-614 Verification
|
||||
|
||||
### Pattern Search: `secure = false` in handlers package
|
||||
|
||||
```
|
||||
grep -rn "secure = false" /projects/Charon/backend/
|
||||
```
|
||||
|
||||
**Result:** 0 matches — ✅ CLEARED
|
||||
|
||||
### Pattern Search: Inline CodeQL suppression
|
||||
|
||||
```
|
||||
grep -rn "codeql[go/cookie-secure-not-set]" /projects/Charon/backend/
|
||||
```
|
||||
|
||||
**Result:** 0 matches — ✅ CLEARED
|
||||
|
||||
### `setSecureCookie` Implementation
|
||||
|
||||
The function unconditionally passes `true` as the `secure` argument to `c.SetCookie`:
|
||||
|
||||
```go
|
||||
c.SetCookie(
|
||||
name, // name
|
||||
value, // value
|
||||
maxAge, // maxAge in seconds
|
||||
"/", // path
|
||||
domain, // domain (empty = current host)
|
||||
true, // secure ← always true, no conditional branch
|

## Security Focus Area Results
|
||||
|
||||
### 1. Credential Handling — `TMP_COOKIE`
|
||||
|
||||
**`mktemp` usage**: `TMP_COOKIE=$(mktemp)` at line 208. Creates a file in `/tmp` with `600` permissions via the OS. ✅ SECURE.
|
||||
|
||||
**Removal on exit**: The `cleanup()` function at line 103 removes the file with `rm -f "${TMP_COOKIE:-}"`. However, `cleanup` is only registered via explicit calls — there is **no `trap cleanup EXIT`**. Only `trap on_failure ERR` is registered (line 108).
|
||||
|
||||
**Gap**: On 5 early `exit 1` paths after line 208 (login failure L220, auth failure L251, Caddy readiness failure L282, security config failure L299, and handler verification failure L316), `cleanup` is never called. The cookie file is left in `/tmp`.
|
||||
|
||||
**Severity**: LOW — The cookie contains session credentials for a localhost test server (`ratelimit@example.local` / `password123`, non-production). CI runners are ephemeral and auto-cleaned. Local runs will leave a `/tmp/tmp.XXXXXX` file until next reboot or manual cleanup.
|
||||
|
||||
**Note**: The exit at line 386 (inside the 429 enforcement failure block) intentionally skips cleanup to leave containers running for manual inspection. This is by design and acceptable.
|
||||
|
||||
**Recommendation**: Add `trap cleanup EXIT` immediately after `trap on_failure ERR` (line 109) to ensure the cookie file is always removed.
|
||||
|
||||
---
|
||||
|
||||
### 2. `curl` — Sensitive Values in Command-Line Arguments
|
||||
|
||||
Cookie file path is passed via `-c ${TMP_COOKIE}` and `-b ${TMP_COOKIE}` (unquoted). No credentials, tokens, or API keys are passed as command-line arguments. All authentication is via the cookie file (read/write by path), which is the correct pattern — cookie values never appear in `ps` output.
|
||||
|
||||
**Finding (LOW)**: `${TMP_COOKIE}` is unquoted in all 6 curl invocations. `mktemp` on Linux produces paths of the form `/tmp/tmp.XXXXXX` which never contain spaces or shell metacharacters under default `$TMPDIR`. However, under a non-standard `$TMPDIR` (e.g., `/tmp/my dir/`) this would break. This is a portability issue, not a security issue.
|
||||
|
||||
**Recommendation**: Quote `"${TMP_COOKIE}"` in all curl invocations.
|
||||
|
||||
---
|
||||
|
||||
### 3. Shell Injection
|
||||
|
||||
All interpolated values in curl `-d` payloads are either:
|
||||
- Script-level constants (`RATE_LIMIT_REQUESTS=3`, `RATE_LIMIT_WINDOW_SEC=10`, `RATE_LIMIT_BURST=1`, `TEST_DOMAIN=ratelimit.local`, `BACKEND_CONTAINER=ratelimit-backend`)
|
||||
- Values derived from API responses stored in double-quoted variables (`"$CREATE_RESP"`, `"$SEC_CONFIG_RESP"`)
|
||||
|
||||
No shell injection vector exists. All heredoc expansions (`cat <<EOF...EOF`) expand only the hardcoded constants listed above.
|
||||
|
||||
The UUID extraction pattern at line 429 includes `${TEST_DOMAIN}` unquoted within a `grep -o` pattern, but because the variable expands to `ratelimit.local` (controlled constant), this has no injection risk. The `.` in `ratelimit.local` is treated as a regex wildcard but in this context only matches the intended hostname. ✅ PASS.
|
||||
|
||||
---
|
||||
|
||||
### 4. `set -euo pipefail` Compatibility
|
||||
|
||||
The new status-capture idiom:
|
||||
|
||||
```bash
|
||||
LOGIN_STATUS=$(curl -s -w "\n%{http_code}" ... | tail -n1)
|
||||
```
|
||||
|
||||
Behavior under `set -euo pipefail`:
|
||||
- **Network failure** (curl exits non-zero, e.g., `ECONNREFUSED`): `pipefail` propagates curl's non-zero exit through the pipeline; the assignment fails; `set -e` fires the `on_failure` ERR trap and exits. ✅ Correct.
|
||||
- **HTTP error** (curl exits 0, HTTP 4xx/5xx): curl outputs `\n{code}`; `tail -n1` extracts the code; assignment succeeds; subsequent `[ "$LOGIN_STATUS" != "200" ]` detects the failure. ✅ Correct.
|
||||
- **Empty body edge case**: If curl returns an empty body, output is `\n200`. `tail -n1` → `200`; `head -n-1` → empty string. Status check still works. ✅ Correct.
|
||||
|
||||
The `SEC_CONFIG_RESP` split pattern (`tail -n1` for status, `head -n-1` for body) is correct for both single-line and multiline JSON responses. ✅ PASS.
|
||||
|
||||
---
|
||||
|
||||
### 5. Workflow Secrets Exposure
|
||||
|
||||
The workflow (`rate-limit-integration.yml`) contains **no `${{ secrets.* }}` references**. All test credentials are hardcoded constants in the script (`ratelimit@example.local` / `password123`), appropriate for an ephemeral test user that is registered and used only within the test run.
|
||||
|
||||
`$GITHUB_STEP_SUMMARY` output includes: container status, API config JSON, container logs. None of these contain secrets or credentials. The security config JSON may contain rate limit settings (integers) but nothing sensitive.
|
||||
|
||||
No accidental log exposure identified. ✅ PASS.
|
||||
|
||||
---
|
||||
|
||||
### 6. GeoIP Change — Supply-Chain Risk
|
||||
|
||||
**Change**: The non-CI Dockerfile build path previously ran `sha256sum -c -` against `GEOLITE2_COUNTRY_SHA256`. This was removed. The remaining guard is `[ -s /app/data/geoip/GeoLite2-Country.mmdb ]` (file-size non-empty check).
|
||||
|
||||
**Risk assessment** (MEDIUM): The download source is `https://github.com/P3TERX/GeoLite.mmdb/raw/download/GeoLite2-Country.mmdb`, a public GitHub repository. If this repository is compromised or the file is replaced with a malicious binary:
|
||||
- The `-s` check only verifies the file is non-empty
|
||||
- The application loads it at `CHARON_GEOIP_DB_PATH` for IP geolocation — a non-privileged read operation
|
||||
- A malicious file would not achieve RCE via MMDb parsing in the MaxMind reader library (no known attack surface), but could corrupt GeoIP lookups silently
|
||||
|
||||
**This is an acknowledged, pre-existing architectural limitation** documented in the spec. The `sha256sum` check was ineffective by design because the P3TERX repository updates the file continuously while the pinned hash only updates weekly via `update-geolite2.yml`. The new behavior (accept any non-empty file) is more honest about the actual constraint.
|
||||
|
||||
**Spec compliance**: `ARG GEOLITE2_COUNTRY_SHA256` is **retained** in the Dockerfile (line ~441) as required by the spec, preserving `update-geolite2.yml` workflow compatibility. ✅ PASS.
|
||||
|
||||
**Residual risk**: MEDIUM. Mitigated by: (1) `wget` uses HTTPS to fetch from GitHub (TLS in transit), (2) downstream Trivy scans of the built image would flag a malicious MMDB independently, (3) the GeoIP reader is sandboxed to a read operation with no known parse-exploit surface.

## Correctness Against Spec
|
||||
|
||||
| Spec Change | Implemented | Verified |
|
||||
|-------------|-------------|----------|
|
||||
| C1: Login status check (Step 4) | ✅ Yes — `LOGIN_STATUS` checked, fails fast on non-200 | Script lines 211–220 |
|
||||
| C2: Proxy host creation — auth failures fatal, 409 continues | ✅ Yes — 401/403 abort, other non-201 continues | Script lines 248–256 |
|
||||
| C3: Caddy admin API readiness gate before security config POST | ✅ Yes — 20-retry loop before SEC_CFG call | Script lines 274–284 |
|
||||
| C4: Security config POST status checked | ✅ Yes — `SEC_CONFIG_STATUS` checked, body logged on error | Script lines 286–301 |
|
||||
| C5: `verify_rate_limit_config` failure is hard exit | ✅ Yes — prints debug and `exit 1` | Script lines 307–318 |
|
||||
| C6: Pre-verification sleep increased 5 → 8 s | ✅ Yes — `sleep 8` | Script line 305 |
|
||||
| C7: Trailing slash on `/config/` | ✅ Yes — all 6 script occurrences; workflow line 71 | Confirmed by grep |
|
||||
| Dockerfile: sha256sum removed from non-CI path | ✅ Yes — only `-s` check remains | Dockerfile lines ~453–463 |
|
||||
| Dockerfile: `ARG GEOLITE2_COUNTRY_SHA256` retained | ✅ Yes — line ~441 | Dockerfile audited |
|
||||
| Workflow: debug dump uses `/config/` | ✅ Yes — line 71 | Confirmed by grep |

## Findings Summary
|
||||
|
||||
| ID | Severity | Area | Description |
|
||||
|----|----------|------|-------------|
|
||||
| M1 | MEDIUM | Dockerfile supply-chain | GeoIP downloaded without hash; `-s` is minimum viability only. Accepted trade-off per spec — hash was perpetually stale. |
|
||||
| L1 | LOW | Shell security | `${TMP_COOKIE}` unquoted in 6 curl invocations. No practical impact under standard `$TMPDIR`. |
|
||||
| L2 | LOW | Temp file hygiene | No `trap cleanup EXIT`; TMP_COOKIE and containers not cleaned on 5 early failure paths (lines 220, 251, 282, 299, 316). Low sensitivity (localhost test credentials only). |
|
||||
|
||||
No CRITICAL or HIGH severity findings.
|
||||
|
||||
---
|
||||
|
||||
## Overall Verdict
|
||||
|
||||
**✅ APPROVED**
|
||||
|
||||
All spec-required changes are correctly implemented. No OWASP Top 10 vulnerabilities were introduced. The two LOW findings (unquoted variable, missing EXIT trap) are hygiene improvements that do not block the fix. The MEDIUM GeoIP supply-chain concern is a pre-existing architectural trade-off explicitly acknowledged in the spec.
|
||||
|
||||
### Recommended follow-up (non-blocking)
|
||||
|
||||
Add `trap cleanup EXIT` immediately after `trap on_failure ERR` in `scripts/rate_limit_integration.sh` to ensure TMP_COOKIE is always removed and containers are cleaned on all exit paths.
|
||||
**Purpose:** Allow admins to set a setting to an empty string value (required to fix the fresh-install CrowdSec enabling bug where `value` was legitimately empty).
|
||||
|
||||
---
|
||||
|
||||
## Overall Verdict: APPROVED
|
||||
|
||||
All structural, linting, and security gates pass. The change is correctly scoped to the build-only `frontend-builder` stage and introduces no new attack surface in the final runtime image.

## 1. Dockerfile Structural Verification
|
||||
|
||||
### Global ARG block (lines 25–40)
|
||||
|
||||
```
|
||||
29: # renovate: datasource=npm depName=npm
|
||||
30: ARG NPM_VERSION=11.11.1
|
||||
```
|
||||
|
||||
Both the Renovate comment and the pinned ARG are present in the correct order. Renovate will track `npm` releases on `datasource=npm` and propose version bumps automatically.
|
||||
|
||||
### frontend-builder stage (lines 93–115)
|
||||
|
||||
```
|
||||
93: FROM --platform=$BUILDPLATFORM node:24.14.0-alpine@sha256:... AS frontend-builder
|
||||
...
|
||||
105: ARG NPM_VERSION

109: npm cache clean --force
|
||||
...
|
||||
111: RUN npm ci
|
||||
```
|

|
||||
|
||||
---
|
||||
|
||||
## 3. Logical Security Review
|
||||
|
||||
### Attack surface — build-only stage
|
||||
|
||||
The `frontend-builder` stage is strictly a build artifact producer. The final runtime image receives only compiled frontend assets via a single targeted `COPY`:
|
||||
|
||||
```
|
||||
COPY --from=frontend-builder /app/frontend/dist /app/frontend/dist
|
||||
```
|
||||
|
||||
The Alpine OS packages upgraded by `apk upgrade --no-cache`, the globally installed npm binary, and all `node_modules` are confined to the builder layer and never reach the runtime image. The CVE remediation has zero footprint in the deployed container.
|
||||
|
||||
### `--no-audit` flag
|
||||
|
||||
`--no-audit` suppresses npm audit output during `npm install -g npm@${NPM_VERSION}`. This applies only to the single-package global npm tool upgrade, not to the project dependency installation. `npm ci` on line 111 installs project dependencies from `package-lock.json` and is unaffected by this flag. Suppressing audit during a build-time tool upgrade is the standard pattern for avoiding advisory database noise that cannot be acted on during the image build.
|
||||
|
||||
### `npm cache clean --force`
|
||||
|
||||
Clears the npm package cache between the global npm upgrade and the `npm ci` run. This is safe: it ensures the freshly installed npm binary is used without stale cache entries left by the older npm version bundled in the base image. The `--force` flag suppresses npm's deprecation warning about manual cache cleaning; it does not alter the clean operation itself.

# Supply Chain Security Scan Report — CVE Investigation
|
||||
|
||||
**Date**: 2026-03-19
|
||||
**Scope**: Charon project at `/projects/Charon`
|
||||
**Tools**: Grype 0.109.1, Syft 1.42.2
|
||||
**Go Toolchain**: go1.26.1
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
The CVEs flagged for `goxmldsig`, `buger/jsonparser`, and `jackc/pgproto3/v2` are **false positives for the Charon project**. These packages are not in Charon's Go module dependency graph. They originate from Go build info embedded in third-party compiled binaries shipped inside the Docker image — specifically the CrowdSec and Caddy binaries.
|
||||
|
||||
`CVE-2026-33186` (`google.golang.org/grpc`) is **resolved in Charon's own source code** (bumped to v1.79.3), but the same CVE still appears in the SBOM because older grpc versions are embedded in the CrowdSec (`v1.74.2`) and Caddy (`v1.79.1`) binaries in the Docker image. Those are out-of-scope for Charon to patch directly.
|
||||
|
||||
The most actionable findings are stale compiled Charon binaries built with go1.25.4–go1.25.6 that carry Critical/High stdlib CVEs and should be rebuilt with the current go1.26.1 toolchain.
|
||||
|
||||
---
|
||||
|
||||
## 1. Root Cause: Why These Packages Appear in Scans
|
||||
|
||||
### Mechanism: go-module-binary-cataloger
|
||||
|
||||
When Syft generates the SBOM from the Docker image (not from source), it uses the **`go-module-binary-cataloger`** to read embedded Go build info from all compiled Go binaries in the image. Every Go binary compiled since Go 1.18 embeds a complete list of its upstream module dependencies via `debug/buildinfo`.
|
||||
|
||||
This means Syft finds packages from *any* Go binary on the image filesystem — including third-party tools like CrowdSec and Caddy — and reports them as if they were Charon dependencies.
|
||||
|
||||
### Confirmed Binary Sources
|
||||
|
||||
| Package | Version | Binary Path | Binary's Main Module |
|
||||
|---|---|---|---|
|
||||
| `github.com/buger/jsonparser` | v1.1.1 | `/usr/local/bin/crowdsec`, `/usr/local/bin/cscli` | `github.com/crowdsecurity/crowdsec` |
|
||||
| `github.com/jackc/pgproto3/v2` | v2.3.3 | `/usr/local/bin/crowdsec`, `/usr/local/bin/cscli` | `github.com/crowdsecurity/crowdsec` |
|
||||
| `github.com/russellhaering/goxmldsig` | v1.5.0 | `/usr/bin/caddy` | `caddy` |
|
||||
| `google.golang.org/grpc` | v1.74.2 | `/usr/local/bin/crowdsec`, `/usr/local/bin/cscli` | `github.com/crowdsecurity/crowdsec` |
|
||||
| `google.golang.org/grpc` | v1.79.1 | `/usr/bin/caddy` | `caddy` |
|
||||
|
||||
**Verification**: None of these packages appear in `backend/go.mod`, `backend/go.sum`, or the output of `go mod graph`.
|
||||

### Why `grype dir:.` Flags Module Cache Artifacts
|
||||
|
||||
Running `grype dir:.` over the Charon workspace also scans `.cache/go/pkg/mod/` — the local Go module download cache. This directory contains the `go.mod` files of every transitively downloaded module. Grype reads those `go.mod` files and flags vulnerable version references within them, even though those versions are not compiled into the Charon binary. All module-cache findings have locations beginning with `/.cache/go/pkg/mod/` and are not exploitable in Charon.
|
||||
|
||||
### Stale SBOM: `sbom-generated.json`
|
||||
|
||||
`sbom-generated.json` (dated **2026-02-21**) was generated by an earlier workflow before the grpc bump and uses a format with no version or PURL data. Grype reading this file matches vulnerabilities against package names alone with no version filter, inflating findings. The authoritative SBOM is `sbom.cyclonedx.json` (dated **2026-03-18**, generated by Syft 1.42.2).

### CVE-2026-33186 — `google.golang.org/grpc`
|
||||
|
||||
| Aspect | Detail |
|
||||
|---|---|
|
||||
| **Charon source (backend/go.mod)** | v1.79.3 — **PATCHED** ✓ |
|
||||
| **CrowdSec binary (`/usr/local/bin/crowdsec`)** | v1.74.2 — out of scope |
|
||||
| **Caddy binary (`/usr/bin/caddy`)** | v1.79.1 — out of scope |
|
||||
| **False positive for Charon?** | Partially — Charon's own code is patched. SBOM findings persist from Docker image binaries. |
|
||||
|
||||
**Remediation**: Upgrade the CrowdSec and Caddy Docker image versions. The fix in Charon's source is complete.

## 3. Actionable Findings
|
||||
|
||||
### 3.1 Stdlib CVEs in Stale Charon Binaries (Critical/High)
|
||||
|
||||
Grype found Charon binaries on-disk compiled with old Go versions. The current toolchain is **go1.26.1**, which patches all of the following.
|
||||
|
||||
| Binary | Go Version | Notable CVEs |
|
||||
|---|---|---|
|
||||
| `.trivy_logs/charon_binary` | go1.25.4 (Nov 2025 artifact) | CVE-2025-68121 (Critical), CVE-2025-61726/29/31/32 (High) |
|
||||
| `backend/bin/charon`, `backend/bin/api`, `backend/bin/charon-debug` | go1.25.6 | CVE-2025-68121 (Critical), CVE-2025-61732 (High), CVE-2026-25679 (High) |
|
||||
| `backend/api` (root-level) | go1.25.7 | CVE-2026-25679 (High), CVE-2026-27142 (Medium) |
|
||||
|
||||
**CVE-2025-68121** (Critical, Go stdlib) is the single highest-severity finding in this report.
|
||||
|
||||
**Remediation**: Rebuild all binaries with go1.26.1. Delete `.trivy_logs/charon_binary` (stale Nov 2025 artifact) or add `.trivy_logs/` to `.gitignore`.
|
||||

|
||||
|
||||
### 3.2 Python Virtual Environment Packages (Dev Tooling Only)
|
||||
|
||||
Local `.venv` directories contain outdated packages. These are not shipped in the Docker image.
|
||||
|
||||
| Severity | ID | Package | Fix |
|
||||
|---|---|---|---|
|
||||
| High | GHSA-8rrh-rw8j-w5fx | wheel 0.45.1 | `pip install --upgrade wheel` |
|
||||
| High | GHSA-58pv-8j8x-9vj2 | jaraco-context 5.3.0 | `pip install --upgrade setuptools` |
|
||||
| Medium | GHSA-597g-3phw-6986 | virtualenv 20.35.4 | `pip install --upgrade virtualenv` |
|
||||
| Medium | GHSA-qmgc-5h2g-mvrw / GHSA-w853-jp5j-5j7f | filelock 3.20.0 | `pip install --upgrade filelock` |
|
||||
| Low | GHSA-6vgw-5pg2-w6jp | pip 24.0 / 25.3 | `pip install --upgrade pip` |
|
||||
|

|
||||
|
||||
### 3.3 Module Cache False Positives (All Confirmed Non-Exploitable)
|
||||
|
||||
Flagged solely because they appear in `go.mod` files inside `.cache/go/pkg/mod/`, not in any compiled Charon binary:
|
||||
|
||||
| ID | Package | Flagged Version | Cache Source | Actual Charon Version |
|
||||
|---|---|---|---|---|
|
||||
| GHSA-p77j-4mvh-x3m3 (Critical) | google.golang.org/grpc | v1.67.0 | `containerd/errdefs/go.mod` | v1.79.3 |
|
||||
| GHSA-9h8m-3fm2-qjrq (High) | go.opentelemetry.io/otel/sdk | v1.38.0 | `otelhttp@v0.63.0/go.mod` | v1.42.0 |
|
||||
| GHSA-47m2-4cr7-mhcw (High) | github.com/quic-go/quic-go | v0.54.0 | `gin-gonic/gin@v1.11.0/go.mod` | not a direct dep |
|
||||
| GHSA-hcg3-q754-cr77 (High) | golang.org/x/crypto | v0.26.0 | `quic-go@v0.54.1/go.mod` | v0.46.0 |
|
||||
| GHSA-cxww-7g56-2vh6 (High) | actions/download-artifact | v4 | `docker/docker` GH workflows in cache | N/A |

## 4. Scan Configuration Recommendations
|
||||
|
||||
### Exclude Go Module Cache from `grype dir:.`
|
||||
|
||||
Create `.grype.yaml` at project root:
|
||||
|
||||
```yaml
|
||||
ignore:
|
||||
- package:
|
||||
location: "**/.cache/**"
|
||||
- package:
|
||||
location: "**/node_modules/**"
|
||||
```
|
||||
|
||||
Alternatively, scan the SBOM directly rather than the filesystem: `grype sbom:sbom.cyclonedx.json`.
|
||||
|
||||
### Regenerate or Remove `sbom-generated.json`
|
||||
|
||||
`sbom-generated.json` (Feb 21 2026) contains packages with no version or PURL data, causing name-only vulnerability matching. Delete it or regenerate with: `syft scan dir:. -o cyclonedx-json > sbom-generated.json`.
|
||||
|
||||
### Delete or Gitignore `.trivy_logs/charon_binary`
|
||||
|
||||
The 23MB stale binary `.trivy_logs/charon_binary` (go1.25.4, Nov 2025) is a Trivy scan artifact causing several Critical/High CVE findings. Add `.trivy_logs/*.binary` or the whole `.trivy_logs/` directory to `.gitignore`.
