Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

MP-7 Media Use
addresses: CWE-434

Requiring identifiable owners for portable devices reduces the attack surface for unrestricted uploads of dangerous file types via anonymous media.

SC-44 Detonation Chambers
addresses: CWE-434

Dangerous file uploads can be detonated in the chamber to determine malice before any production write or execution occurs.

SC-51 Hardware-based Protection
addresses: CWE-434

Prevents unrestricted writing of arbitrary or malicious firmware by keeping hardware write-protect enabled except under tightly controlled manual procedures.

SI-3 Malicious Code Protection
addresses: CWE-434

Scans files from external sources on download/open/execute, blocking unrestricted uploads of dangerous file types.

PR.PS-05 mostly match
prevents

Restricting execution of unauthorized software directly blocks dangerous uploaded files from running.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent use of the deprecated PHP upload globals and variable-overwrite flaws.

PR.PS-01 partial match
prevents

Hardened configuration baselines can enforce allowed file types and processing rules.

A.8.29 Security testing in development and acceptance mostly match
finds

Configuration and acceptance testing verify that file-upload handling enforces allowed types and does not permit dangerous content to be stored or executed.

A.8.25 Secure development life cycle partial match
prevents

Secure-coding guidelines and security testing explicitly address restrictions on allowed file types and upload handling, reducing the risk that dangerous file uploads are accepted without validation.

A.8.26 Application security requirements partial match
prevents

Application security requirements include secure file-upload mechanisms that eliminate reliance on the four legacy PHP variables.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles discourage unsafe global state, indirectly reducing exposure to variable-injection attacks.

A.8.28 Secure coding partial match
prevents

Secure coding explicitly prohibits use of deprecated upload variables and requires validated, server-side file handling.

A.8.30 Outsourced development partial match
prevents

Mandated testing for malicious content and known vulnerabilities reduces the likelihood that an outsourced component will contain or accept dangerous file types that could later be uploaded or executed.
