- Implement database-level controls: Use least privilege database accounts, enable query logging, and implement database firewall rules
🔍 How to Verify
Check if Vulnerable:
Test the firstname parameter in /teacher_signup.php with SQL injection payloads like ' OR '1'='1 and observe database errors or unexpected behavior.Check Version:
Check application version in admin panel or review source code comments for version information.Verify Fix Applied:
After implementing fixes, test with the same SQL injection payloads and verify they are properly sanitized or blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed signup attempts with SQL patterns
- Database queries with unusual syntax from web server IP
Network Indicators:
- HTTP POST requests to /teacher_signup.php containing SQL keywords (UNION, SELECT, INSERT, etc.)
- Abnormal response patterns from the signup endpoint
SIEM Query:
source="web_logs" AND uri="/teacher_signup.php" AND (request_body LIKE "%UNION%" OR request_body LIKE "%SELECT%" OR request_body LIKE "%INSERT%")
