Mitigating Controls (NIST 800-53 r5) AI

AC-6 Least Privilege good match
prevent

Directly requires that default permissions grant only the minimum access needed, preventing the overly permissive Partner Integration defaults described in the CVE.

AC-3 Access Enforcement good match
prevent

Enforces access decisions on protected resources, ensuring the incorrect default permissions cannot be exploited to access Tanium integration data.

CM-6 Configuration Settings partial match
prevent

Requires secure configuration of system settings, including explicit correction of insecure default permission values before deployment.

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-01 full match
prevents

Hardened baselines and configuration management explicitly require correct default file permissions.

PR.AA-05 mostly match
prevents

Defining and enforcing least-privilege access permissions directly prevents overly permissive defaults at install time.

ID.AM-08 partial match
prevents

Lifecycle management can encompass permission settings, yet the control is too broad to specifically mitigate incorrect defaults.

PR.PS-06 partial match
prevents

Secure SDLC practices include establishing secure defaults, but address only the development-phase portion of the weakness.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

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.8.9 Configuration management mostly match
prevents

Standard templates that restrict access to utility programs and host parameter settings prevent the assignment of overly permissive default permissions on critical resources.
