NIST 800-53 r5 controls PROPOSED for this weakness (4)AI-assisted

These are model PROPOSALS, not graded mappings. They come from controls_to_cwe_proposals, which carries no grade field at all; across the CWE pages 1,540 of 1,722 such associations (89%) have never been graded by anything. The heading said “address” until 2026-09-29, which asserted a relationship the data does not carry. Graded cross-walks are on the framework map, not here.

Control Title Family Why it addresses this CWE
SI-3Malicious Code ProtectionSIgraded mostly Scans files from external sources on download/open/execute, blocking unrestricted uploads of dangerous file types.
SC-44Detonation ChambersSCDangerous file uploads can be detonated in the chamber to determine malice before any production write or execution occurs.
SC-51Hardware-based ProtectionSCPrevents unrestricted writing of arbitrary or malicious firmware by keeping hardware write-protect enabled except under tightly controlled manual procedures.
MP-7Media UseMPRequiring identifiable owners for portable devices reduces the attack surface for unrestricted uploads of dangerous file types via anonymous media.
