SI-2 Flaw Remediation good match
prevent

Mandates prompt remediation of the known SQL injection flaw in the Document Management System 1.0 code.

SC-7 Boundary Protection partial match
prevent

Boundary protection devices such as WAFs can inspect and drop remote SQL injection attempts targeting deluser.php.
