Subject: Ivanti Workspace Control Application Whitelist bypass via PowerGrid

------------------------------------------------------------------------
Ivanti Workspace Control Application Whitelist bypass via PowerGrid /RWS
command line argument
------------------------------------------------------------------------
Yorick Koster, August 2018

------------------------------------------------------------------------
Abstract
------------------------------------------------------------------------
It was found that the PowerGrid application will execute rundll32.exe
from a relative path when it is started with the /RWS command line
option. An attacker can abuse this issue to bypass Application
Whitelisting in order to run arbitrary code on the target machine.

------------------------------------------------------------------------
Tested versions
------------------------------------------------------------------------
This issue was successfully verified on Ivanti Workspace Control version
10.2.700.1.

------------------------------------------------------------------------
Fix
------------------------------------------------------------------------
This issue was resolved in Ivanti Workspace Control version 10.2.950.0.
PowerGrid now uses the GetSystemDirectory() function to construct an
absolute path to rundll32.exe.
