Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-2 Flaw Remediation good match
prevent

Remediating the specific flaw in the Rosebud WordPress theme by patching to a non-vulnerable version directly eliminates the PHP Local File Inclusion vulnerability.

SI-10 Information Input Validation good match
prevent

Validating user-supplied filenames used in PHP include/require statements prevents attackers from injecting paths to arbitrary local files.

CM-6 Configuration Settings partial match
prevent

Establishing secure PHP configuration settings, such as open_basedir restrictions, limits the impact of Local File Inclusion by confining file access to authorized directories.
