Check software version in admin panel or review installation files for version indicators.Verify Fix Applied:
Test with SQL injection payloads after implementing fixes - should return proper error messages or no database errors.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts following SQL errors
- HTTP requests with SQL keywords in searchdata parameter
Network Indicators:
- HTTP POST requests to /search-notice.php containing SQL injection patterns
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/search-notice.php" AND (searchdata CONTAINS "UNION" OR searchdata CONTAINS "SELECT" OR searchdata CONTAINS "OR 1=1")
