Description

This module exploits a vulnerability in Microsoft Silverlight. The vulnerability exists on
the Initialize() method from System.Windows.Browser.ScriptObject, which access memory in an
unsafe manner. Since it is accessible for untrusted code (user controlled) it's possible
to dereference arbitrary memory which easily leverages to arbitrary code execution. In order
to bypass DEP/ASLR a second vulnerability is used, in the public WriteableBitmap class
from System.Windows.dll. This module has been tested successfully on IE6 - IE10, Windows XP
SP3 / Windows 7 SP1.
