|
||||
|
||||
## 🚀 Remediation Priority
|
||||
|
||||
### Week 1 (Immediate - HIGH Priority)
|
||||
1. **Agent Binary Injection** - Implement code signing verification
|
||||
2. **Account Enumeration** - Fix constant-time responses (always 401)
|
||||
3. **Timing Attack** - Replace `==` with `hmac.compare_digest()`
|
||||
|
||||
### Weeks 2-4 (Short-term - MEDIUM Priority)
|
||||
4. **Rate Limit Bypass** - Add rate limiting to /refresh endpoint
|
||||
5. **Token Non-Rotation** - Implement refresh token rotation
|
||||
6. **Upload DoS** - Add rate limiting to upload endpoints
|
||||
|
||||
### Month 2+ (Long-term - LOW Priority)
|
||||
7. **Race Condition** - Implement SELECT FOR UPDATE or ON CONFLICT
|
||||

|

|
||||
## 📊 Validation Options for Unvalidated Findings
|
||||
|
||||
### Option 1: Automated Validation (Recommended)
|
||||
- **Cost**: $15-20
|
||||
- **Time**: 30-45 minutes
|
||||
- **Outcome**: Confirm 6-8 real vulnerabilities, reject 32-34 false positives
|
||||
- **Command**: `python audit.py --resume --budget 80`
|
||||
|
||||
### Option 2: Manual Review by Priority
|
||||
1. File upload validation (8 findings) - Similar to HIGH severity confirmed vuln
|
||||
2. Rate limiting gaps (7 findings) - Similar to MEDIUM severity confirmed vuln
|
||||
3. Token management (3 findings) - Similar to MEDIUM severity confirmed vuln
|
||||
4. Race conditions (6 findings) - Similar to LOW severity confirmed vuln
|
||||
5. Other findings (low priority)
|
||||
|
||||
### Option 3: Accept Risk
|
||||
- Focus only on 7 confirmed vulnerabilities
|
||||
- Address unvalidated findings in future audit cycles
|
||||
- Accept potential false negatives (missing 6-8 real vulns)
