The version of VMware Tools installed on the remote Windows host is 11.x, which is prior to 11.3.0. It is, therefore, affected by a denial-of-service vulnerability in the VM3DMP driver. A malicious actor with local user privileges in the Windows guest operating system, where VMware Tools is installed, can trigger a PANIC in the VM3DMP driver leading to a denial-of-service condition in the Windows guest operating system.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
