'Description' => %q{  
This module exploits a vulnerability on 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 on both x32 and x64 architectures.
