  • Block external access to /changeidproof.php endpoint using firewall rules
  • Implement network segmentation to isolate the system from internet access

🔍 How to Verify

Check if Vulnerable:

Test /changeidproof.php endpoint with SQL injection payloads in editid parameter

Check Version:

Check system documentation or configuration files for version information

Verify Fix Applied:

Attempt SQL injection tests and verify they are blocked or sanitized
