- Implement strict network segmentation and monitor all database queries
🔍 How to Verify
Check if Vulnerable:
Test /search-visitor.php with SQL injection payloads like ' OR '1'='1 in searchdata parameterCheck Version:
Check system documentation or admin panel for version informationVerify Fix Applied:
Test with same payloads; system should reject or sanitize input without executing SQL📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts after search queries
- Long or malformed search parameters in web logs
Network Indicators:
- HTTP POST requests to /search-visitor.php with SQL keywords in parameters
- Unusual database connection patterns
SIEM Query:
source="web_logs" AND uri="/search-visitor.php" AND (searchdata CONTAINS "UNION" OR searchdata CONTAINS "SELECT" OR searchdata CONTAINS "OR '1'='1")
