Check if Vulnerable:
Test the search functionality with SQL injection payloads like ' OR '1'='1 in searchdata parameterCheck Version:
Check system documentation or contact vendor for version informationVerify Fix Applied:
Test with same payloads after implementing fixes - should return no data or error messages📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed search attempts with special characters
- Unexpected database queries from web server
Network Indicators:
- HTTP POST requests to /search-result.php containing SQL keywords (UNION, SELECT, INSERT)
- Abnormal database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/search-result.php" AND (searchdata CONTAINS "UNION" OR searchdata CONTAINS "SELECT" OR searchdata CONTAINS "' OR '")
