🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing custom fixes.
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation for PATH_INFO parameter in /job-details endpoints
Modify PHP code to sanitize $_SERVER['PATH_INFO'] using preg_replace('/[^a-zA-Z0-9\-\_]/', '', $input)
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns in URL paths
Add WAF rule: SecRule REQUEST_URI "@rx (?i)(union|select|insert|update|delete|drop|create|alter).*" "id:1001,phase:2,deny"
🧯 If You Can't Patch
- Isolate the vulnerable system behind a reverse proxy with strict input filtering
- Implement network segmentation to limit database access from web servers
🔍 How to Verify
Check if Vulnerable:
Test with payload: /job-details/1' OR '1'='1 and observe database errors or unexpected behaviorCheck Version:
Check software version in admin panel or readme filesVerify Fix Applied:
Attempt SQL injection payloads and verify they are rejected or sanitized without database errors📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in web server logs
- Unusual database query patterns from web application
- Multiple failed parameter parsing attempts
Network Indicators:
- HTTP requests with SQL keywords in URL paths
- Abnormal database connection patterns from web servers
SIEM Query:
source="web_logs" AND (url="*job-details*" AND (url="*union*" OR url="*select*" OR url="*' OR '*"))
