CVE-2025-15289 Overview
CVE-2025-15289 is an improper access controls vulnerability (CWE-862: Missing Authorization) affecting Tanium Interact. This vulnerability allows authenticated users with low privileges to potentially access sensitive information through the network due to missing or inadequate authorization checks in the application.
Critical Impact
Authenticated attackers may exploit insufficient access controls to gain unauthorized read access to sensitive data within Tanium Interact environments.

Technical Details for CVE-2025-15289
Vulnerability Analysis
This vulnerability stems from improper access control implementation in Tanium Interact. The flaw is classified under CWE-862 (Missing Authorization), indicating that the application fails to properly enforce authorization checks when processing certain requests. This allows authenticated users to access resources or functionality beyond their intended permission scope.
The vulnerability requires network access and authenticated credentials to exploit, though the attack complexity is considered high. Successful exploitation could result in unauthorized disclosure of limited confidential information. The attack does not require user interaction and has no impact on system integrity or availability.
Root Cause
The root cause is a missing authorization vulnerability where Tanium Interact does not adequately verify that users have the appropriate permissions before granting access to protected resources. When authorization checks are absent or improperly implemented, the application may process requests from authenticated users without validating whether they should have access to the requested data or functionality.
Attack Vector
The attack vector is network-based, requiring the attacker to have low-privilege authenticated access to the Tanium Interact platform. Due to the high attack complexity, specific conditions must be met for successful exploitation. The attacker would need to identify and exploit the missing authorization checks to access information that should be restricted to higher-privileged users.
The vulnerability allows for limited confidentiality impact with no integrity or availability consequences. This suggests the flaw enables read-only access to certain data rather than allowing modification or disruption of services.
Detection Methods for CVE-2025-15289
Indicators of Compromise
- Unusual access patterns from low-privilege user accounts attempting to access restricted resources
- Authentication logs showing users accessing endpoints or data outside their normal scope
- Audit trail entries indicating authorization failures followed by successful unauthorized access
Detection Strategies
- Review Tanium Interact access logs for anomalous data access patterns by authenticated users
- Monitor for authentication events followed by access to resources outside the user's normal permissions
- Implement user and entity behavior analytics (UEBA) to detect privilege boundary violations
Monitoring Recommendations
- Enable detailed audit logging for all access control decisions in Tanium Interact
- Configure alerts for access attempts to sensitive data by users who have not previously accessed such resources
- Regularly review access control configurations and user permission assignments
How to Mitigate CVE-2025-15289
Immediate Actions Required
- Review the Tanium Security Advisory TAN-2025-033 for official guidance
- Audit current user permissions in Tanium Interact and enforce principle of least privilege
- Monitor access logs for any signs of exploitation until patches can be applied
Patch Information
Tanium has addressed this vulnerability. Organizations should consult the official Tanium Security Advisory TAN-2025-033 for specific patch information, affected versions, and upgrade instructions. Contact Tanium support if additional guidance is needed for your deployment.
Workarounds
- Restrict network access to Tanium Interact to trusted IP ranges and VPN connections only
- Implement additional authorization controls at the network or proxy layer pending patch deployment
- Review and minimize user accounts with access to Tanium Interact, removing unnecessary privileges
