CVE-2025-15288 is an authorization vulnerability identified in Tanium Interact version 3.5.0, a component of the Tanium endpoint management and security platform widely used in enterprise environments. The flaw arises from improper access control mechanisms that fail to adequately restrict certain user actions, allowing a user with low privileges to access data or functionality beyond their authorization scope. According to the CVSS 3.1 vector (AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N), exploitation requires network access but has a high attack complexity, meaning that an attacker must overcome significant hurdles to exploit the vulnerability. The attacker needs only low privileges and no user interaction is required, but the impact is limited to confidentiality with no effect on integrity or availability. No known exploits have been reported in the wild, and no patches or exploit code links are currently provided, indicating that this vulnerability is either newly disclosed or not yet actively targeted. Tanium Interact is used for querying and managing endpoints, so unauthorized read access could expose sensitive operational data or system information. However, the limited scope and low severity reduce the immediate risk. Organizations should monitor Tanium advisories for patches and consider tightening access controls and auditing user permissions to mitigate potential exploitation.

For European organizations, the primary impact of CVE-2025-15288 is the potential unauthorized disclosure of sensitive information managed through Tanium Interact. While the vulnerability does not allow modification or disruption of services, unauthorized read access could expose operational details, endpoint data, or security telemetry that may aid further attacks or leak confidential information. Organizations in sectors with high regulatory requirements for data confidentiality, such as finance, healthcare, and critical infrastructure, could face compliance risks if sensitive data is exposed. The high attack complexity and requirement for network access limit the likelihood of widespread exploitation, but targeted attacks against high-value targets remain a concern. The absence of known exploits reduces immediate threat levels, but the presence of low-privileged access abuse could be leveraged as a foothold in multi-stage attacks. European enterprises relying on Tanium for endpoint management should assess their exposure, especially if running the affected version 3.5.0, and prepare for timely patch deployment.

1. Apply official patches or updates from Tanium as soon as they become available to remediate the improper access control issue. 2. In the interim, review and tighten user role assignments and permissions within Tanium Interact to ensure least privilege principles are enforced, minimizing the number of users with access to sensitive query capabilities. 3. Implement network segmentation and restrict access to Tanium Interact interfaces to trusted management networks only, reducing exposure to potential attackers. 4. Enable and regularly review audit logs for unusual or unauthorized query activity that could indicate exploitation attempts. 5. Conduct internal penetration testing or vulnerability assessments focusing on Tanium Interact access controls to identify and remediate weaknesses. 6. Educate administrators and security teams on the vulnerability details and encourage vigilance for suspicious behavior related to endpoint management tools. 7. Monitor threat intelligence feeds and Tanium advisories for updates on exploit developments or additional mitigation guidance.
