Check if Vulnerable:
Test the /registeracc.php endpoint with SQL injection payloads in the email parameter (e.g., email=test' OR '1'='1)Check Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection payloads no longer execute and return proper error handling📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed registration attempts with suspicious email patterns
Network Indicators:
- HTTP POST requests to /registeracc.php containing SQL keywords in parameters
SIEM Query:
source="web_logs" AND uri="/registeracc.php" AND (email CONTAINS "' OR" OR email CONTAINS "UNION" OR email CONTAINS "SELECT")
