Summary

CVE-2024-38522 is a medium-severity Permissive List of Allowed Inputs (CWE-183) vulnerability in Hushline Hush Line. Its CVSS base score is 6.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Obfuscated Files or Information (T1027); ranked at the 28th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation directly exercises security-relevant comparisons to discover incorrect logic.

SI-10 Information Input Validation good match

Strict validity checks on inputs directly stop overly permissive allow lists from being used as the protection mechanism.

AC-25 Reference Monitor partial match

A reference monitor must be small and correct, structurally limiting the chance of flawed comparison logic in authorization decisions.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles require correct implementation of comparison logic used for access and authentication decisions.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require rigorous allow-list design and testing that prevents permissive input validation.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

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

Security testing can detect overly broad allow-lists, but does not inherently prevent their creation.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle includes code review and testing that can catch incorrect comparison logic.

A.8.26 Application security requirements partial match
prevents

Application security requirements can mandate strict, minimal allow-lists and input validation rules that prevent overly permissive lists.

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

Secure system architecture and engineering principles require explicit, least-privilege input validation designs that directly address permissive allow-lists.

A.8.28 Secure coding partial match
prevents

Secure coding standards enforce rigorous input validation and reject unsafe values, mitigating permissive allow-list weaknesses.

A.8.5 Secure authentication partial match
degrades

Secure authentication mechanisms rely on correct comparison of credentials or tokens.
