Original NVD Description

VMware Tools for Windows (11.x.y prior to 11.2.6), VMware Remote Console for Windows (12.x prior to 12.0.1) , VMware App Volumes (2.x prior to 2.18.10 and 4 prior to 2103) contain a local privilege escalation vulnerability. An attacker with normal access to a virtual machine may exploit this issue by placing a malicious file renamed as `openssl.cnf' in an unrestricted directory which would allow code to be executed with elevated privileges.
