WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns
Add WAF rule: deny requests containing SQL keywords in searchdata parameter
🧯 If You Can't Patch
- Isolate the system behind a reverse proxy with strict input validation
- Implement network segmentation to limit database access from the application server
🔍 How to Verify
Check if Vulnerable:
Test /search-result.php with SQL injection payloads in searchdata parameterCheck Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection attempts no longer succeed and return proper error handling📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple rapid requests to /search-result.php with suspicious parameters
Network Indicators:
- HTTP POST requests to /search-result.php containing SQL keywords like UNION, SELECT, INSERT
SIEM Query:
source="web_logs" AND uri="/search-result.php" AND (searchdata CONTAINS "UNION" OR searchdata CONTAINS "SELECT" OR searchdata CONTAINS "INSERT")
