🔍 How to Verify
Check if Vulnerable:
Test the /admin_class.php?action=login endpoint with SQL injection payloads in the Username parameterCheck Version:
Check the software version in the admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection payloads no longer execute and return proper error handling📡 Detection & Monitoring
Log Indicators:
