🔍 How to Verify
Check if Vulnerable:
Test /request.php endpoint with SQL injection payloads in staff_id parameter and observe database errors or unexpected behaviorCheck Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Attempt SQL injection tests after implementing fixes and confirm no database errors or unauthorized data access occurs📡 Detection & Monitoring
Log Indicators:
- Unusual database queries from web server
- SQL syntax errors in application logs
- Multiple failed parameter validation attempts
Network Indicators:
- HTTP requests to /request.php containing SQL keywords (UNION, SELECT, INSERT, etc.) in parameters
SIEM Query:
source="web_logs" AND uri="/request.php" AND (param="*UNION*" OR param="*SELECT*" OR param="*INSERT*")
