Summary

VMware ESXi, Workstation, and Fusion have a vulnerability within the USB 2.0 controller (EHCI) that allows a malicious actor with local administrative privileges on a virtual machine to exploit this flaw. Successful exploitation could lead to the execution of arbitrary code within the virtual machine's VMX process on the host system. On ESXi, this exploitation is restricted to the VMX sandbox, while on Workstation and Fusion, it has the potential to execute code directly on the host machine. Maintaining the latest security patches is crucial for safeguarding against this vulnerability.

Affected Version(s)

VMware ESXi, VMware Workstation Pro / Player, VMware Fusion Pro / Fusion (Fusion), VMware Cloud Foundation VMware ESXi (8.0 prior to ESXi80a-20842819, 7.0 prior to ESXi70U3si-20841705, VMware Workstation Pro / Player (16.x prior to 16.2.5), VMware Fusion Pro / Fusion (12.x prior to 12.2.5), VMware Cloud Foundation (4.x, 3.x)

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
