Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-2 Flaw Remediation good match
prevent

Directly remediates the specific flaw in the Tiger Claw theme's PHP include/require statements that allow improper filename control leading to local file inclusion.

SI-10 Information Input Validation good match
prevent

Validates user-supplied filenames prior to their use in PHP include/require operations to block malicious local file inclusion paths.

CM-6 Configuration Settings partial match
prevent

Enforces secure PHP configuration settings like open_basedir to limit the filesystem paths accessible via include/require statements, mitigating LFI exploitation.
