Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation of inputs such as the ID parameter before processing, preventing the SQL injection payload from reaching the database.
Enforces access control checks on /admin/manage_register.php so that unauthenticated remote requests are denied before any parameter processing occurs.
Restricts the privileges available to the web application process or unauthenticated sessions, limiting the impact even if an injection succeeds.
