feat: complete Phase 2 testing infrastructure remediation and discovery
## Summary - Phase 2.1 critical fixes implemented and verified: * Uptime monitor initial state logic validated (no code change needed) * Backups guest authorization check added (frontend role gating) * Docker integration element IDs fixed for test selector reliability - Phase 2.2 discovery completed with root cause analysis: * User management invite endpoint identified: blocking email send (SMTP blocking) * Docker integration code quality verified as sound * Async email pattern recommended for Phase 2.3 implementation - Comprehensive QA verification executed: * Full Phase 2 E2E suite run in headless mode (90%+ pass rate) * GORM security scanner passed (0 CRITICAL/HIGH app code issues) * Infrastructure validation complete (Docker, ports, containers operational) ## Critical Findings - CVE-2024-45337 in golang.org/x/crypto/ssh (dependency update required) - InviteUser handler blocks on SMTP (design pattern issue, documented for async refactor) - Test authentication token refresh needed for Phase 3 ## Artifacts Created - Phase 2 discovery documents (user management, Docker integration) - Uptime monitor contract test validating initial state behavior - Comprehensive security and quality reports in docs/reports/ and docs/security/ ## Next Steps 1. Update crypto dependency (1 hour) - CRITICAL 2. Implement async email queuing for invites (2-3 hours) - HIGH 3. Add test auth token refresh mechanism (30 min) - MEDIUM 4. Phase 3 security enforcement testing can proceed in parallel

### Step 1: Update Direct Dependencies
|
||||
|
||||
```bash
|
||||
cd /projects/Charon/backend
|
||||
|
||||
# Update crypto (CRITICAL)
|
||||
go get -u golang.org/x/crypto@latest
|
||||
|
||||
# Update net
|
||||
go get -u golang.org/x/net@latest
|
||||
|
||||
# Update oauth2
|
||||
go get -u golang.org/x/oauth2@latest
|
||||
|
||||
# Update quic-go
|
||||
go get -u github.com/quic-go/quic-go@latest
|
||||
|
||||
# Clean up
|
||||
go mod tidy
|
||||
go mod verify
|
||||
```
|
||||
|
||||
### Step 2: Verify Updates
|
||||
|
||||
```bash
|
||||
# Check updated versions
|
||||
go list -u -m all | grep -E "x/crypto|x/net|x/oauth2|quic-go"
|
||||
|
||||
# List all vulnerabilities
|
||||
go list -json -m all | go-vuln-check 2>/dev/null || echo "Install go-vuln-check for detailed report"
|
||||
|
||||
# Re-run Trivy
|
||||
trivy fs . --severity CRITICAL,HIGH --format sarif -o /tmp/trivy-post-update.sarif
|
||||
```
|
||||
|
||||
### Step 3: Build & Test
|
||||
|
||||
```bash
|
||||
# Rebuild container
|
||||
docker build -t charon:local .
|
||||
|
||||
# Run tests
|
||||
npx playwright test tests/core tests/settings tests/tasks tests/monitoring
|
||||
|
||||
# Container scan
|
||||
trivy image charon:local --severity CRITICAL,HIGH
|
||||
```
|
||||
|
||||
### Step 4: Commit & Deploy
|
||||
|
||||
```bash
|
||||
git add go.mod go.sum
|
||||
git commit -m "chore: update dependencies to fix CVE-2024-45337 and related security issues"
|
||||
git push
|
||||
```

|
||||
## Dependency Risk Assessment
|
||||
|
||||
### Why These CVEs Matter
|
||||
|
||||
1. **SSH Authentication** (CVE-2024-45337, CVE-2025-22869)
|
||||
- Risk: Reverse proxy manages SSH connectivity
|
||||
- Impact: Potential auth bypass if SSH is enabled
|
||||
- Likelihood: Medium (depends on SSH configuration)
|
||||
|
||||
2. **HTTP/2 Attacks** (CVE-2022-41721, CVE-2023-39325)
|
||||
- Risk: Caddy proxy serves HTTP/2, DoS possible
|
||||
- Impact: Service unavailability via stream reset attacks
|
||||
- Likelihood: High (publicly known attack vectors)
|
||||
|
||||
3. **Token Handling** (CVE-2025-22868)
|
||||
- Risk: OAuth2 token processing vulnerable
|
||||
- Impact: Memory exhaustion or token parsing failure
|
||||
- Likelihood: Medium
|
||||
|
||||
4. **QUIC Crashes** (CVE-2025-59530)
|
||||
- Risk: QUIC is used for HTTPS
|
||||
- Impact: Connection termination, DoS
|
||||
- Likelihood: Medium
|
||||
|
||||
### Overall Risk Rating
|
||||
|
||||
**Current Risk Level:** ⚠️ MEDIUM-HIGH
|
||||
**Post-Update Risk Level:** ✅ LOW
|
||||
**Update Priority:** 🔴 IMMEDIATE (within 24 hours)

3. Configure CI to run on dependency PRs
|
||||
4. Set up scheduled Trivy scans
|
||||
|
||||
### Configuration
|
||||
|
||||
**.github/dependabot.yml:**
|
||||
```yaml
|
||||

|
||||
directory: "/backend"
|
||||
schedule:
|
||||
interval: "weekly"
|
||||
open-pull-requests-limit: 5
|
||||
reviewers:
|
||||
- "security-team"
|
||||
- package-ecosystem: "npm"
|
||||
directory: "/frontend"
|
||||
schedule:
|
||||
interval: "weekly"
|
||||
```
|
||||
|
||||
### Regular Scanning
|
||||
|
||||
```bash
|
||||
# Weekly vulnerability scan
|
||||
0 0 * * 0 cd /projects/Charon && trivy fs . --severity CRITICAL,HIGH --format json > trivy-weekly.json
|
||||
|
||||
# Monthly deep review
|
||||
0 0 1 * * cd /projects/Charon && go list -u -m all > go-dependencies.txt
|
||||
```
