Description

The version of VMware Tools installed on the remote Windows host is 10.3.x, 11.x or 12.x prior to 12.3.5. It is, therefore, affected by a SAML token signature bypass vulnerability. A malicious actor that has been granted Guest Operation Privileges in a target virtual machine may be able to elevate their privileges if that target virtual machine has been assigned a more privileged Guest Alias.

Solution

Upgrade to VMware Tools version 12.3.5 or later.
