CVE-2025-15288 identifies an improper access control vulnerability in Tanium Interact version 3.5.90. Tanium Interact is a platform used for endpoint management and security operations, enabling querying and interaction with managed devices. The vulnerability arises from incorrect authorization checks that allow a user with low privileges to access certain resources or data that should be restricted. According to the CVSS v3.1 vector (AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N), exploitation requires network access with low privileges and high attack complexity, but no user interaction. The impact is limited to a low confidentiality loss, with no impact on integrity or availability. Tanium has acknowledged the issue and published it in the CVE database, but no public exploits have been reported. The vulnerability affects version 3.5.90, and organizations running this version should monitor for patches or updates from Tanium. The flaw could potentially allow unauthorized data access within the platform, which may expose sensitive endpoint information or operational details, but the scope is limited by the required privileges and complexity.

For European organizations, the impact of CVE-2025-15288 is relatively low due to the limited confidentiality impact and the requirement for an attacker to have low privileges and network access. However, Tanium Interact is often used in large enterprises and critical infrastructure sectors for endpoint management and security operations, so any unauthorized access could reveal sensitive operational data or endpoint details. This could aid an attacker in reconnaissance or lateral movement if combined with other vulnerabilities. The lack of integrity or availability impact means system operations are not directly disrupted. Organizations in regulated sectors with strict data protection requirements (e.g., finance, healthcare) should consider the confidentiality implications carefully. Overall, the vulnerability represents a moderate operational risk but not an immediate critical threat.

1. Apply patches or updates from Tanium as soon as they become available to address the improper access control issue. 2. Review and tighten role-based access controls (RBAC) within Tanium Interact to ensure users have the minimum necessary privileges. 3. Monitor network access to Tanium Interact servers, restricting access to trusted IP ranges and using network segmentation to limit exposure. 4. Enable detailed logging and audit trails for user actions within Tanium Interact to detect any unauthorized access attempts. 5. Conduct regular security assessments and penetration tests focusing on access control mechanisms in endpoint management platforms. 6. Educate administrators and users on the importance of credential security and monitoring for suspicious activity. 7. Consider deploying additional endpoint detection and response (EDR) tools to detect lateral movement attempts that could leverage this vulnerability.
