Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly remediates the local privilege escalation vulnerability in Tanium Patch Endpoint Tools by requiring timely patching as specified in Tanium's security advisory TAN-2025-001.

AC-6 Least Privilege partial match

prevent

Mitigates privilege escalation by ensuring users and processes interacting with Tanium Patch Endpoint Tools operate with least privileges necessary.

SI-4 System Monitoring partial match

detect

Enables identification of exploitation through monitoring for anomalous privilege changes or unauthorized access on endpoints running vulnerable Tanium tools.

NVD Description

Tanium addressed a local privilege escalation vulnerability in Patch Endpoint Tools.

Deeper analysisAI

CVE-2025-15310 is a local privilege escalation vulnerability (CWE-59) affecting Tanium's Patch Endpoint Tools. Tanium addressed the issue, which carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). The vulnerability was published on 2026-02-10T00:16:05.370.

A local attacker with low privileges (PR:L) can exploit the vulnerability with low attack complexity and no user interaction. Successful exploitation enables high-impact compromise of confidentiality, integrity, and availability, allowing privilege escalation on affected endpoints.

Tanium has published security advisory TAN-2025-001 at https://security.tanium.com/TAN-2025-001, which provides details on the vulnerability and associated remediation.
