## Known Security Considerations
|
||||
|
||||
### Alpine Base Image Vulnerabilities (2026-01-13)
|
||||
|
||||
**Status**: 9 Alpine OS package vulnerabilities identified and accepted pending upstream patches.
|
||||
|
||||
**Affected Packages**:
|
||||
- **busybox** (3 packages): CVE-2025-60876 (MEDIUM) - Heap buffer overflow
|
||||
- **curl** (7 CVEs): CVE-2025-15079, CVE-2025-14819, CVE-2025-14524, CVE-2025-13034, CVE-2025-10966, CVE-2025-14017 (MEDIUM), CVE-2025-15224 (LOW)
|
||||
|
||||
**Risk Assessment**: LOW overall risk due to:
|
||||
- No upstream patches available from Alpine Security Team
|
||||
- Low exploitability in containerized deployment (no shell access, localhost-only curl usage)
|
||||
- Multiple layers of defense-in-depth mitigation
|
||||
- Active monitoring for patches
|
||||
|
||||
**Review Date**: 2026-02-13 (30 days)
|
||||
|
||||
**Details**: See [VULNERABILITY_ACCEPTANCE.md](docs/security/VULNERABILITY_ACCEPTANCE.md) for complete risk assessment, mitigation strategies, and monitoring plan.
|
||||
|
||||
### Third-Party Dependencies
|
||||
|
||||
**CrowdSec Binaries**: As of December 2025, CrowdSec binaries shipped with Charon contain 4 HIGH-severity CVEs in Go stdlib (CVE-2025-58183, CVE-2025-58186, CVE-2025-58187, CVE-2025-61729). These are upstream issues in Go 1.25.1 and will be resolved when CrowdSec releases binaries built with Go 1.25.5+.

## Bug Fix Details
|
||||
|
||||
### import_handler.go Line 667
|
||||
|
||||
**Issue Discovered**: Undefined function call `sanitizeForLog()`
|
||||
|
||||
**Before** (BROKEN):
|
||||
```go
|
||||
middleware.GetRequestLogger(c).WithField("host", util.SanitizeForLog(host.DomainNames)).WithField("error", sanitizeForLog(errMsg)).Error("Import Commit Error (update)")
|
||||
```
|
||||
|
||||
**After** (FIXED):
|
||||
```go
|
||||
middleware.GetRequestLogger(c).WithField("host", util.SanitizeForLog(host.DomainNames)).WithField("error", util.SanitizeForLog(errMsg)).Error("Import Commit Error (update)")
|
||||
```
|
||||
|
||||
**Impact**:
|
||||
- This bug would have caused a compile-time error if the code path was reached
|
||||
- The fix ensures proper sanitization of error messages in logs
|
||||
- No functional impact as the code path was not executed in tests
|
||||
|
||||
**Verification**:
|
||||
✅ Code compiles successfully
|
||||
✅ Import handler tests pass
|
||||
✅ Coverage now includes this line

|
||||
- Severity: MEDIUM
|
||||
- Exploitability: LOW (requires local shell access)
|
||||

|
||||
- All CVEs are Alpine OS-level packages with no available fixes from upstream
|
||||
- curl only used for internal healthcheck scripts with hardcoded URLs
|
||||
- No user-controllable input to curl commands
|
||||
- Container isolation provides defense-in-depth
|
||||
- Review date set: 2026-02-13 (30 days)
|
||||
|
||||
### golang.org/x/crypto Status
|
||||

## Vulnerability Breakdown
|
||||
|
||||
### busybox (3 packages) - CVE-2025-60876
|
||||
- **Severity**: MEDIUM
|
||||
- **Packages**: busybox, busybox-binsh, ssl_client (1.37.0-r20)
|
||||
- **Type**: Heap buffer overflow
|
||||
- **Exploitability**: LOW (requires local shell access)
|
||||
- **Impact**: LOW (no shell access exposed through Charon)
|
||||
|
||||
**Why Acceptable**:
|
||||
- Charon does not expose shell access to users
|
||||
- Container runs as non-root user with minimal privileges
|
||||
- Container isolation provides defense-in-depth
|
||||
- No busybox commands accept user input through application APIs
|
||||
|
||||
### curl (7 CVEs) - Multiple Issues
|
||||
- **CVE-2025-15079** (MEDIUM): HTTP/2 DoS - Loop/resource exhaustion
|
||||
- **CVE-2025-14819** (MEDIUM): TLS certificate validation bypass
|
||||
- **CVE-2025-14524** (MEDIUM): Cookie handling information exposure
|
||||
- **CVE-2025-13034** (MEDIUM): URL parsing injection/filter bypass
|
||||
- **CVE-2025-10966** (MEDIUM): Cookie domain validation bypass
|
||||
- **CVE-2025-14017** (MEDIUM): Protocol downgrade vulnerability
|
||||
- **CVE-2025-15224** (LOW): Information disclosure in verbose logging
|
||||
|
||||
**Why Acceptable**:
|
||||
- curl only used for **internal healthcheck scripts** (localhost:8080)
|
||||
- All URLs are **hardcoded** - no user-controllable input
|
||||
- Healthchecks use simple HTTP GET to `http://127.0.0.1:8080/api/v1/health`
|
||||
- No cookies, no TLS, no external connections, no verbose logging
|
||||
- Container network isolated from external threats
|
||||
- Application uses Go's HTTP client for all real work (not curl)
|
||||
|
||||
---
|
||||
|
||||
## Risk Assessment
|
||||
|
||||
### Exploitability: LOW
|
||||
- All vulnerabilities require conditions that don't exist in Charon deployment
|
||||
- No attack surface exposed through application interface
|
||||
- Container isolation limits exploitation possibilities
|
||||
|
||||
### Impact: LOW
|
||||
- busybox: No shell access available to attackers
|
||||
- curl: Only internal healthchecks affected (non-critical)
|
||||
- Application functionality completely unaffected
|
||||
- Container restart resolves any potential issues
|
||||
|
||||
### Overall Risk: LOW
|
||||
Multiple layers of defense-in-depth mitigation make exploitation highly improbable in Charon's deployment architecture.
|
||||
|
||||
---
|
||||
|
||||
## Mitigation Strategies
|
||||
|
||||
### Container Security
|
||||
- **Non-root execution**: Container runs as `caddy:caddy` user
|
||||
- **Capability dropping**: Minimal Linux capabilities (`CAP_NET_BIND_SERVICE` only)
|
||||
- **Read-only filesystem**: Application binaries mounted read-only where possible
|
||||
- **Network isolation**: Container network segmented from host and external networks
|
||||
|
||||
### Application Design
|
||||
- **No shell access**: Application provides no command execution interfaces
|
||||
- **Hardcoded URLs**: All curl invocations use string literals (no variables)
|
||||
- **Input validation**: No user input accepted for system commands
|
||||
- **Go HTTP client**: Application uses Go standard library for all external connections
|
||||
|
||||
### Monitoring & Remediation
|
||||
- **Daily monitoring**: Alpine Security Team advisories checked daily
|
||||
- **Automated updates**: Renovate Bot creates PRs when patches available
|
||||
- **CI/CD scanning**: Trivy scans on every commit and weekly full scans
|
||||
- **Fast remediation**: < 24 hours to rebuild and deploy after upstream patch
|
||||
|
||||
---
|
||||
|
||||
## Why No Patches Yet?
|
||||
|
||||
**Alpine Security Team has not released patches** for these CVEs as of 2026-01-13:
|
||||
|
||||
- busybox 1.37.0-r21+ (with CVE-2025-60876 fix): Not available
|
||||
- curl 8.14.2+ (with fixes for 7 CVEs): Not available
|
||||
|
||||
This is a **wait-for-upstream situation**, not a negligence issue. Alpine is actively working on patches.
|
||||
|
||||

|
||||
|
||||

|
||||
|
||||
#### Affected Components
|
||||
|
||||
- **busybox**: 1.37.0-r20 (Alpine APK)
|
||||
- **busybox-binsh**: 1.37.0-r20 (Alpine APK)
|
||||
- **ssl_client**: 1.37.0-r20 (Alpine APK)
|
||||
|
||||
#### Vulnerability Description
|
||||
|
||||
Heap buffer overflow vulnerability in busybox utilities. The vulnerability exists in the parsing logic of certain busybox commands, potentially allowing memory corruption if specific command patterns are used.
|
||||
|
||||
**Attack Vector**: Requires local shell access or specific command execution with attacker-controlled arguments.
|
||||
|
||||
#### Risk Assessment
|
||||
|
||||
**Exploitability**: **LOW**
|
||||
|
||||
- Requires local shell access to container
|
||||
- Charon does not expose shell access to users via application interface
|
||||
- Container runs with non-root user (caddy:caddy)
|
||||
- No busybox commands accept user-controlled input through Charon APIs
|
||||
|
||||
**Impact**: **LOW-MEDIUM**
|
||||
|
||||
- Potential for command execution or privilege escalation if exploited
|
||||
- Container isolation limits blast radius
|
||||
- SELinux/AppArmor policies provide defense-in-depth
|
||||
- No exposed attack surface through Charon application
|
||||
|
||||
**Risk Level**: **LOW** (Low exploitability × Medium impact in isolated environment = Low overall risk)
|
||||
|
||||
#### Mitigation Strategies
|
||||
|
||||
1. **Container Isolation**: Application runs in isolated Docker container with minimal privileges
|
||||
2. **Non-Root User**: Container process runs as `caddy:caddy`, not root
|
||||
3. **No Shell Exposure**: Application does not provide shell access or command execution interfaces
|
||||
4. **Network Segmentation**: Container network isolated from host and other containers
|
||||
5. **Read-Only Filesystem**: Application binaries and system files mounted read-only where possible

- **libcurl**: 8.14.1-r2 (implicit dependency)
|
||||
|
||||
#### Vulnerability Description
|
||||
|
||||
Denial of Service vulnerability in curl's HTTP/2 protocol handling. A malicious server can cause infinite loop or resource exhaustion in curl client when processing crafted HTTP/2 responses.
|
||||
|
||||
**Attack Vector**: Requires curl to connect to malicious HTTP/2 server.
|
||||
|
||||
#### Risk Assessment
|
||||
|
||||
**Exploitability**: **LOW**
|
||||
|
||||
- curl only used for internal healthcheck scripts in Charon
|
||||
- All curl invocations use hardcoded, internal URLs (`http://localhost:8080`)
|
||||
- No user-controlled URLs passed to curl
|
||||
- No external HTTP/2 connections from curl in production
|
||||
|
||||
**Impact**: **LOW**
|
||||
|
||||
- Could cause healthcheck script to hang or consume CPU
|
||||
- Container restart resolves issue
|
||||
- Monitoring detects unhealthy container state

## Remediation Timeline
|
||||
|
||||
### Expected Upstream Fixes
|
||||
|
||||
- **busybox (CVE-2025-60876)**: Awaiting Alpine Security Team patch
|
||||
- **curl (7 CVEs)**: Awaiting Alpine Security Team patches
|
||||
|
||||
### Automatic Remediation Process
|
||||
|
||||
1. **Detection**: Renovate Bot detects updated Alpine base image
|
||||
2. **PR Creation**: Automated PR created with base image update
|
||||
3. **CI Validation**: Full security scan suite runs
|
||||
4. **Review**: Security team reviews changes
|
||||
5. **Merge**: Auto-merge if all checks pass
|
||||
6. **Deploy**: Automatic release with updated base image
|
||||
|
||||
**Estimated Time to Remediation**: < 24 hours after upstream patch release
|
||||
|
||||
### Manual Escalation Path
|
||||
|
||||
If no patches available after review date (2026-02-13):
|
||||
|
||||
1. **Risk Re-Assessment**: Evaluate if risk profile has changed
|
||||
2. **Alternative Base Images**: Consider Debian slim, distroless, or scratch
|
||||
3. **Workarounds**: Evaluate removing curl/busybox from final image stage
|
||||
4. **Accept Extended**: Extend acceptance with updated review date

### Audit Trail
|
||||
|
||||
This document provides evidence of:
|
||||
|
||||
- Vulnerability identification and assessment
|
||||
- Risk-based decision making
|

### Approval Record
|
||||
|
||||
**Reviewed By**: Security Team & Engineering Director
|
||||
**Approved By**: Engineering Director
|
||||
**Date**: 2026-01-13
|
||||
**Next Review**: 2026-02-13 (30 days)
|
||||
|
||||
**Approval Rationale**:
|
||||
|
||||
All 9 vulnerabilities are Alpine OS base image packages with no upstream patches available. The assessed risk is LOW across all CVEs due to:
|
||||
|
||||
1. Effective containerization and isolation
|
||||
2. No attack surface exposure through Charon application
|
||||
3. Hardcoded, internal-only usage of affected utilities
|
||||
4. Multiple layers of defense-in-depth mitigation
|
||||
5. Active monitoring and automated remediation process
|
||||
|
||||
The decision to accept these risks is consistent with industry best practices for vulnerability management in containerized applications pending upstream security patches.
