Summary

CVE-2025-23263 is a high-severity Incorrect Execution-Assigned Permissions (CWE-279) vulnerability in Custhelp (inferred from references). Its CVSS base score is 7.6 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique File and Directory Permissions Modification (T1222); ranked at the 7th 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-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforcing approved authorizations structurally stops the runtime assignment of permissions that violate user intent.

AC-6 Least Privilege good match

Requiring least privilege limits the permissions the executing code is allowed to assign.

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.AA-05 mostly match
prevents

Enforcing policy-defined permissions and least privilege directly prevents runtime permission mis-assignments.

PR.PS-01 partial match
prevents

Hardened configuration baselines and change control reduce the chance of incorrect permission settings during execution.

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.8.18 Use of privileged utility programs partial match
mitigates

Restricting privileged utility programs reduces the chance that such tools will incorrectly alter object permissions.

A.8.2 Privileged access rights partial match
degrades

Privileged access rights management directly constrains the permissions a process may assign at runtime.

A.8.28 Secure coding partial match
prevents

Secure coding practices can prevent the coding error that leads to incorrect permission assignment.

A.8.3 Information access restriction partial match
degrades

Information access restriction policies limit the permissions that executing code can grant or modify.

A.8.32 Change management none match
detects

Change-management procedures can catch permission-setting mistakes before they reach production.
