|

This module exploits a directory traversal vulnerability found in ManageEngine
|
||||
Support Center Plus build 7916 and lower. The module will create a support ticket
|
||||
as a normal user, attaching a link to a file on the server. By requesting our
|
||||
own attachment, it's possible to retrieve any file on the filesystem with the same
|
||||
privileges as Support Center Plus is running. On Windows this is always with SYSTEM
|
||||
privileges.
