Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation and sanitization of untrusted inputs such as difficulty_id before they reach SQL statements, blocking the injection vector in btn_functions.php.
Limits the privileges of the database account used by the application so that a successful SQLi yields only minimal confidentiality/integrity/availability impact.
Requires timely remediation of the known flaw in the publicly released code, eliminating the SQL injection vulnerability at its source.
