Security Issues Resolution TODO

Generated: 2024-01-15
Purpose: Targeted tasks for resolving security vulnerabilities identified in Security Automation Gateway codebase
Priority: Critical (🔴) > High (🟠) > Medium (🟡) > Low (🟢)

  • main.py (line 111) - Hardcoded test password hash

Issues:

  • Base64-encoded secrets are visible in version control
  • Test credentials hardcoded in production code
  • Default/example secrets in Helm values

Tasks:

  • Remove all hardcoded secrets from k8s/secrets/database.yaml and replace with placeholders
  • Remove hardcoded secrets from gitops/helm/values.yaml and use external secret management

  • console/secrets_service.py (lines 37-43)
  • main.py (lines 61-67)

Issues:

  • CORS configured with allow_origins=["*"] allowing any origin
  • allow_credentials=True with wildcard origins (browser security violation)
  • No origin validation

Tasks:

  • Replace wildcard CORS origins with specific allowed origins from environment variables
  • Fix allow_credentials configuration (must be False when using wildcard)
  • Add origin validation middleware
  • Implement CORS policy based on environment (dev/staging/prod)
  • Add CORS configuration to settings.py with validation

Estimated Effort: 2-3 hours

3. Fix TrustedHostMiddleware Configuration

Files Affected:

  • sag/services/gateway.py (lines 949-952)
  • main.py (lines 70-73)

Issues:

  • Add security headers middleware (X-Content-Type-Options, X-Frame-Options, etc.)

Estimated Effort: 1-2 hours

4. Fix Rate Limiting Fail-Open Behavior

Files Affected:

  • sag/services/gateway.py (lines 468-521)

Issues:

Estimated Effort: 3-4 hours

7. Enhance Input Validation

  • Missing validation for JSON structure
  • No validation for file uploads

Tasks:

  • Improve malicious pattern detection (case-insensitive, regex improvements)
  • Add JSON schema validation for request bodies
  • Implement file upload validation (size, type, content scanning)
  • Add request body size limits per endpoint
  • Implement input sanitization for all user inputs
  • Add validation for query parameters

Estimated Effort: 4-5 hours

8. Secure Secret Storage in Console Service

Files Affected:

  • console/secrets_service.py (lines 46-47)

Issues:

  • Secrets stored in plain JSON file

Implementation Notes

Security Principles to Follow:

  1. Fail-Secure Defaults: When in doubt, deny access
  2. Defense in Depth: Multiple layers of security
  3. Least Privilege: Minimal required permissions
  4. Input Validation: Validate and sanitize all inputs
  5. Secure by Default: Secure configuration out of the box

Testing Requirements:

  • All security fixes must include tests
  • Security tests should be run in CI/CD
  • Manual security review required for critical fixes

Review Process:

  1. Code review by security team
  2. Security testing
  3. Documentation update
  4. Deployment to staging
  5. Security validation
  6. Production deployment
