🔍 How to Verify
Check if Vulnerable:
Test /content_top.jsp endpoint with SQL injection payloads in the 'id' parameter (e.g., id=1' OR '1'='1)Check Version:
Check application version through admin interface or configuration filesVerify Fix Applied:
Verify SQL injection attempts no longer succeed and return appropriate error handling📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple requests to /content_top.jsp with SQL keywords in parameters
Network Indicators:
- HTTP requests containing SQL injection patterns targeting /content_top.jsp
SIEM Query:
