- Implement network segmentation to limit database access from application server only
🔍 How to Verify
Check if Vulnerable:
Test login.php with SQL injection payloads like: email=test' OR '1'='1Check Version:
Check system version in admin panel or readme filesVerify Fix Applied:
Test with same payloads after implementing fixes - should return error or no data leakage📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed login attempts with SQL-like patterns
Network Indicators:
- HTTP POST requests to /login.php containing SQL keywords in email parameter
SIEM Query:
source="web_logs" AND uri="/login.php" AND (email CONTAINS "' OR" OR email CONTAINS "UNION" OR email CONTAINS "SELECT")
