Netsweeeper 4.0.8 (and probably other versions) allows an authenticated user with admin privileges on the Cloud Manager web console, to upload arbitrary PHP code (eg PHP shell) and further execute it.

To replicate the bug, pipe the following request while being authenticated using admin privileges: http://netsweeper/webadmin/ajaxfilemanager/ajaxfilemanager.php

From the response page you can upload any GIF-lookalike php shell (remember to use basic evasion technique for file to upload successfully, hint: filename="secuid0.php.gif" with gif like header and php shell following)

Then, access your shell from: https://netsweeper/webadmin/deny/images/secuid0.php.gif and profit.
