Summary

CVE-2025-32462 is a low-severity Incorrect Authorization (CWE-863) vulnerability in Sudo Project Sudo. Its CVSS base score is 2.8 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 11% of CVEs by exploit likelihood; 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 AC-24 (Access Control Decisions) and AC-25 (Reference Monitor) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Sudo before version 1.9.17p1 is affected by an authorization flaw when a sudoers file restricts commands to a host that is neither the current machine nor the ALL wildcard. The issue is tracked as CVE-2025-32462 with a CVSS score of 2.8 and is classified under CWE-863, allowing listed users to bypass intended host-based command restrictions.

A local user who is explicitly permitted to run commands on another host can invoke those commands on the current system instead, because the host check is not enforced correctly in the affected versions. Exploitation requires local access and a crafted sudoers entry but does not need additional user interaction.

Multiple vendor advisories, including those from Red Hat, Debian, Gentoo, and Amazon Linux, reference the CVE and point to updated packages that correct the host-matching logic. Administrators are expected to upgrade to 1.9.17p1 or later and review existing sudoers files for host-specific entries.

The EPSS score reached a peak of 0.3345 after disclosure before settling at 0.3001, indicating measurable post-release interest in the issue despite its low base severity.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

AC-3 directly requires correct enforcement of authorization decisions on every access request, structurally preventing incorrect checks.

AC-24 Access Control Decisions good match

AC-24 ensures access-control decisions are made and applied consistently, reducing the chance of an incorrect authorization result.

AC-25 Reference Monitor good match

A reference monitor that is always invoked and tamper-proof forces every authorization decision through a verified, correct path.

AC-6 Least Privilege partial match

Least-privilege assignments shrink the set of authorizations that must be checked correctly, limiting exposure to flawed checks.

PR.AA-05 mostly match
prevents

Defining, enforcing, and reviewing access authorizations and least privilege directly prevents incorrect authorization checks.

A.5.15 Access control partial match
prevents

Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.

A.5.18 Access rights partial match
prevents

Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.

A.8.3 Information access restriction partial match
prevents

By tying access rights to identity, device, location and classification, the control reduces the likelihood that an authorization decision will be based on an incorrect or bypassed policy.
