allDeploy WAF with SQL injection protection rules
🧯 If You Can't Patch
- Implement strict input validation for all ID parameters
- Restrict database user permissions to minimum required access
🔍 How to Verify
Check if Vulnerable:
Test Banner.php with SQL injection payloads in ID parameter: Banner.php?ID=1' OR '1'='1Check Version:
Check SEMCMS version in admin panel or configuration filesVerify Fix Applied:
Test with same payloads after fix; should return error or no data instead of executing SQL📡 Detection & Monitoring
