Check if Vulnerable:
Test the fullname parameter in save_user/update_user functions with SQL injection payloads like ' OR '1'='1
Check Version:
Check application version in configuration files or admin panel
Verify Fix Applied:
Verify that parameterized queries are implemented and SQL injection payloads are properly rejected
📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Multiple failed login attempts with SQL patterns
- Database error messages containing user input
Network Indicators:
- HTTP requests with SQL keywords in fullname parameter
- Unusual database connection patterns from application server
SIEM Query:
source="web_logs" AND (fullname CONTAINS "' OR" OR fullname CONTAINS "UNION" OR fullname CONTAINS "SELECT")
