A threat actor with local user privilege to a guest virtual machine can exploit this vulnerability and gain elevated privileges within the virtual machine. The severity of this vulnerability is given as 7.8 (High).
As a prerequisite, a threat actor requires “guest operations privilege” to exploit this vulnerability. This privilege controls the ability to interact with files and applications inside a virtual machine’s guest operating system for exploiting this vulnerability.
A threat actor with this privilege can exploit this vulnerability on a target virtual machine and elevate their privileges if that target virtual machine has been assigned with a more privileged Guest Alias. The severity for this vulnerability has been given as 7.5 (High).
