DescriptionCVE.org

Tanium addressed a SQL injection vulnerability in Asset.

AnalysisAI

SQL injection in the Tanium Asset module allows a remote attacker who already holds a valid Tanium console session with Asset-module authorization to execute arbitrary SQL through an undisclosed injectable input, with high impact to confidentiality, integrity, and availability (CVSS 3.1 8.8, AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). The vulnerability is an authenticated-adjacent issue: the PR:L vector means the attacker must first obtain console credentials and Asset authorization, and the target must have the optional Asset module deployed, which narrows the exposed population below Tanium's overall install base. …

Vulnerability AssessmentAI

Exploitation Requires an authenticated Tanium console session with access to the Asset module (PR:L) reachable over the network (AV:N); no user interaction is needed once authenticated (UI:N). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuine mid-to-high priority issue but not a drop-everything emergency. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Apply the vendor-fixed release of the Tanium Asset module as documented in Tanium security advisory TAN-2026-049 (https://security.tanium.com/TAN-2026-049); because the input data does not include an explicit fixed version string, confirm the exact patched build number in that advisory and upgrade the module rather than assuming the current version is remediated. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, confirm whether the Tanium Asset module is deployed in your environment and, if so, inventory every console account and role that carries Asset-module authorization; review Tanium console and database audit logs for anomalous or unexpected SQL activity, and open a case with Tanium referencing advisory TAN-2026-049 to obtain the fix version and release timeline. …
