🔍 How to Verify
Check if Vulnerable:
Test endpoints with SQL injection payloads: index.php?p=accomodation&q=' OR '1'='1Check Version:
Check software version in admin panel or configuration filesVerify Fix Applied:
Test with same payloads after implementing fixes - should return error or no data📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in logs
- Multiple failed login attempts from single IP
- Long or unusual query parameters
