VMware Tools 10.x < 11.0.0 Privilege Escalation (VMSA-2020-0002)

high Nessus Plugin ID 133208

Synopsis

A virtualization tool suite is installed on the remote Windows host is affected by a privilege escalation vulnerability.

Description

The version of VMware Tools installed on the remote Windows host is 10.x, which is prior to 11.0.0. It is, therefore, affected by a race condition which may allow for privilege escalation in the virtual machine where Tools is installed.
An authenticated, local attacker can exploit this to escalate their privileges on a Windows virtual machine.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to VMware Tools version 11.0.0 or later or apply the workaround mentioned in the vendor advisory.
