Description
This exploits an improper use of setuid binaries within VMware Fusion 10.1.3 - 11.5.3.
The Open VMware USB Arbitrator Service can be launched outide of its standard path
which allows loading of an attacker controlled binary. By creating a payload in the
user home directory in a specific folder, and creating a hard link to the 'Open VMware
USB Arbitrator Service' binary, we're able to launch it temporarily to start our payload
with an effective UID of 0.
@jeffball55 discovered an incomplete patch in 11.5.3 with a TOCTOU race.
Successfully tested against 10.1.6, 11.5.1, 11.5.2, and 11.5.3.
