Summary

CVE-2025-15330 is a high-severity Missing Authorization (CWE-862) vulnerability in Tanium Deploy. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 25.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2025-15330 is an improper input validation vulnerability, classified under CWE-862, affecting Tanium Deploy. Tanium addressed this issue, which was published on 2026-02-05 with a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), marking it as high severity due to its potential for significant impact.

The vulnerability can be exploited by an attacker with low privileges (PR:L) over the network (AV:N), requiring low attack complexity (AC:L) and no user interaction (UI:N). Successful exploitation enables high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H) within the unchanged scope (S:U), potentially allowing unauthorized access, data modification, or disruption of Tanium Deploy services.

Tanium's security advisory TAN-2025-012 provides details on mitigation, available at https://security.tanium.com/TAN-2025-012.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly mitigates the improper input validation vulnerability by requiring validation and corrective action on all information inputs to ensure consistency with expected content.

SI-2 Flaw Remediation good match
prevent

Addresses the specific CVE by requiring timely identification, reporting, and risk-based remediation of software flaws like this high-severity input validation issue.

SI-9 Information Input Restrictions partial match
prevent

Complements input validation by restricting the types and quantities of information permitted at system interfaces, reducing the attack surface for malformed inputs.
