Summary

CVE-2025-71176 is a medium-severity Creation of Temporary File in Directory with Insecure Permissions (CWE-379) vulnerability. Its CVSS base score is 6.8 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked at the 4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-6 (Least Privilege) and SC-4 (Information in Shared System Resources) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

AC-6 Least Privilege good match

AC-6 reduces the set of actors that can reach an insecurely created temp file by limiting privileges on the containing directory.

SC-4 Information in Shared System Resources good match

SC-4 stops unintended information exposure through shared resources such as world-writable temp directories or files.

AC-3 Access Enforcement partial match

AC-3 directly enforces file and directory access authorizations, stopping creation or exposure of temp files under overly permissive ACLs.

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 prevent developers from writing code that creates temp files in insecure directories.

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.8.27 Secure system architecture and engineering principles partial match
prevents

Secure system architecture principles include proper file-system permission models that mitigate insecure temp-file creation.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly require safe temporary-file creation with restrictive permissions.

A.8.3 Information access restriction partial match
mitigates

Information access restriction policies can limit who may read or list files in shared temporary directories.

A.8.9 Configuration management partial match
mitigates

Configuration management can enforce secure default permissions on temporary directories.
