Description

This 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.
The following versions should be vulnerable:
vCenter 7.0 before U2c
vCenter 6.7 before U3o
vCenter 6.5 before U3q
