🔍 How to Verify
Check if Vulnerable:
Test /search-notice.php with SQL injection payloads in searchdata parameter (e.g., searchdata=' OR '1'='1).Check Version:
Check CMS version in admin panel or configuration files.Verify Fix Applied:
Verify that SQL injection attempts no longer succeed and return appropriate error messages.📡 Detection & Monitoring
