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.
-
Verify Windows Admin Center installationCheck if Windows Admin Center is installed on the system. This can be done via Programs and Features, or by checking for the installation directory (typically in Program Files\Windows Admin Center).Affected if Windows Admin Center is installed on the system.
-
Determine installed version numberLocate the installed version of Windows Admin Center. The version is typically available in the installation directory, in an about page accessed through the product UI, or via PowerShell commands that query installed applications.Affected if Unable to determine the installed version.
-
Compare version against affected rangeCompare the identified version against the vulnerable range: versions greater than or equal to 1809 and versions less than 2606 are affected.Affected if The installed version is >= 1809 AND < 2606.
-
Confirm service accessibilityVerify that the Windows Admin Center service is running and accessible on the system, as the vulnerability requires interaction with the service.Affected if The service is running and the version falls within the affected range.
The system is affected if Windows Admin Center is installed with a version >= 1809 and < 2606 and the service is accessible.
