Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and static analysis can discover missing filename restrictions before deployment.

Validating all inputs before they reach include/require statements directly stops untrusted filenames from being used.

Enforcing access authorizations on resources limits what an included file can reach even if a bad name is supplied.

Information-flow rules can block the loading of external or unauthorized files into the PHP process.

PR.PS-01 partial match
blocks

Hardened runtime configuration (e.g., allow_url_include=off) directly blocks RFI even if code is flawed.

PR.PS-05 partial match

Execution restrictions can prevent the remote payload from running, while eliminating the weakness reduces the need for such controls.

PR.PS-06 partial match
blocks

Secure SDLC practices such as input validation and allow-listing of include paths directly prevent the weakness.
