🧯 If You Can't Patch
- Block external access to the vulnerable system using network ACLs or firewall rules
- Implement strict input validation at the application layer for all user inputs
🔍 How to Verify
Check if Vulnerable:
Test the /rms.php?page=users endpoint with SQL injection payloads in the fname parameter (e.g., fname=' OR '1'='1)Check Version:
Check system documentation or about page for version informationVerify Fix Applied:
Test with the same payloads after implementing fixes - should return error or no data instead of executing SQL📡 Detection & Monitoring
