VMware vCenter vScalation Privilege Escalation

Posted on 06 December 2022

This Metasploit module exploits a privilege escalation in vSphere/vCenter due to improper permissions on the /usr/lib/vmware-vmon/java-wrapper-vmon file. It is possible for anyone in the cis group to write to the file, which will execute as root on vmware-vmon service restart or host reboot. This module was successfully tested against VMware VirtualCenter 6.5.0 build-7070488. Vulnerable versions should include vCenter 7.0 before U2c, vCenter 6.7 before U3o, and vCenter 6.5 before U3q.
