Check if /fair/addfair.php exists and accepts ID parameter; test with SQL injection payloads like ' OR '1'='1.Check Version:
Check application documentation or configuration files for version information.Verify Fix Applied:
Verify that SQL injection payloads no longer execute and return error messages or are properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple requests to /fair/addfair.php with suspicious ID parameters
Network Indicators:
- HTTP requests containing SQL keywords (SELECT, UNION, etc.) in URL parameters
SIEM Query:
source="web_logs" AND url="/fair/addfair.php" AND (param="ID" AND value CONTAINS "' OR" OR value CONTAINS "UNION" OR value CONTAINS "SELECT")
