Sun xVM VirtualBox < 1.6.4 Local Privilege Escalation

This script is Copyright (C) 2008-2017 Tenable Network Security, Inc.


Synopsis :

The remote Windows host has an application that is affected by a local
privilege escalation vulnerability.

Description :

The remote host contains a version of Sun xVM VirtualBox, an open
source virtualization platform, before 1.6.4. Such versions reportedly
include a kernel driver, 'VBoxDrv.sys', that allows a local user to
open the device '\\.\VBoxDrv' and issue IOCTLs with a buffering method
of 'METHOD_NEITHER' without any validation. Using specially crafted
input, an unprivileged user can leverage this issue to execute
arbitrary code in kernel mode.
