Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Tanium Connect versionLocate the Tanium Connect version through the Tanium Console: Navigate to Administration > Plugins > Tanium Connect, or check the Tanium Connect service details via the Tanium Server management interface. The version is typically displayed in the plugin information panel.Affected if The installed version falls within these ranges: >= 5.26.0 and < 5.26.191, OR >= 5.29.0 and < 5.29.237, OR >= 5.37.0 and < 5.37.140
-
Confirm Tanium Connect service is runningCheck if the Tanium Connect service is active on the Tanium Server. This can be verified through the Tanium Console under Services or via command line on the server host using system service management tools.Affected if Tanium Connect service is running and the version matches the affected ranges from step 1
-
Verify Connect module exposureDetermine if the Tanium Connect web interface or API endpoints are accessible from network locations. Check firewall rules, reverse proxy configurations, or load balancer settings that expose the Connect service.Affected if The Connect service is network-accessible and the version is within the affected ranges - this indicates potential remote exploitation vectors
A system is affected if Tanium Connect is installed with a version matching any of the three affected ranges (5.26.0-5.26.190, 5.29.0-5.29.236, or 5.37.0-5.37.139) and the Connect service is active.
