CVE-2025-15314
Tanium End-User-Cx 1.4 – 1.4.1175
Raw vector
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2025-15314 is a medium-severity Link Following (CWE-59) vulnerability in Tanium End-User-Cx. Its CVSS base score is 5.5 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Path Interception (T1034); ranked at the 26th 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.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-15314 is an arbitrary file deletion vulnerability affecting Tanium's end-user-cx component. Published on 2026-02-10, the issue has a CVSS v3.1 base score of 5.5 (AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N) and is associated with CWE-59 (Improper Link Resolution Before File Access) as well as NVD-CWE-noinfo. Tanium has addressed the vulnerability.
A local attacker with low privileges, such as a standard user account on the affected system, can exploit this vulnerability with low complexity and no user interaction required. Successful exploitation enables high-impact integrity violations, specifically arbitrary file deletion, without affecting confidentiality or availability.
Tanium's security advisory TAN-2025-010, available at https://security.tanium.com/TAN-2025-010, provides details on mitigation and patches for this vulnerability.

V15.4.2
Mitigating Controls (NIST 800-53 r5) AI
Proper enforcement of access authorizations on the resolved target resource stops a link from reaching an unintended object.
Least-privilege limits the damage an attacker can cause after following an unintended link.
Validating file-name inputs can reject or canonicalize names that resolve to links before access occurs.
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.
Secure SDLC practices directly require code to validate paths and avoid unsafe link following.

Security testing can detect link-following flaws before release.
Secure SDLC practices can mandate link-resolution checks and canonicalization before file access.
Application security requirements can explicitly require safe handling of symbolic links and path traversal.
Secure architecture principles include input validation and safe file-access design patterns.
Secure coding standards directly address canonicalization and symlink attacks during implementation.
Access-control rules can limit which files are reachable, reducing exposure to malicious links.
