Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-2 Flaw Remediation good match
prevent

Timely remediation of the PHP Local File Inclusion flaw in the full-customer WordPress plugin directly eliminates the vulnerability preventing exploitation.

SI-10 Information Input Validation good match
prevent

Validating user-supplied filenames for proper format and absence of path traversal sequences before PHP include/require operations prevents local file inclusion attacks.

CM-6 Configuration Settings partial match
prevent

Hardening PHP configuration settings such as open_basedir restrictions and disabling allow_url_include mitigates risks of improper filename controls in vulnerable plugins.
