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.
-
Confirm Zoom VDI client is installedCheck the system for Zoom VDI client installation using Add/Remove Programs on Windows, or package management tools on Linux VDI platformsAffected if Zoom VDI client software is present on the system
-
Identify installed Zoom VDI client versionLocate the Zoom VDI client installation and retrieve its version number from the program properties, installer metadata, or version information embedded in the executableAffected if The installed version number is less than 5.14.0
-
Verify the VDI client service is activeCheck if the Zoom VDI client service or daemon is running on the system, as the vulnerability manifests when the client is installed and operationalAffected if The VDI client is installed and running with a version below 5.14.0
The environment is affected if Zoom Virtual Desktop Infrastructure client is installed with a version lower than 5.14.0, as the improper access control flaw allows local privilege escalation via unauthorized file deletion.
