- Implement network monitoring for SQL injection attempts and failed login patterns
🔍 How to Verify
Check if Vulnerable:
Test login page with SQL injection payloads in username/password fields. Example: ' OR '1'='1Check Version:
Check web interface version at login page or device settings. Hardware version may require physical inspection.Verify Fix Applied:
Verify SQL injection attempts no longer bypass authentication. Test with same payloads that should fail.📡 Detection & Monitoring
