Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation of all inputs (including the Username argument to /curvus2/signup.php) to reject malformed or SQL-special-character data before it reaches the database.
Boundary-protection mechanisms such as a WAF or database firewall can inspect and block the SQL-injection payloads sent over the network to the registration endpoint.
Continuous monitoring of web-application and database traffic can identify anomalous SQL syntax or error patterns originating from unauthenticated registration requests.
