Sendmail MAIL FROM Command Arbitrary Remote Command Execution

This script is Copyright (C) 1999-2016 Tenable Network Security, Inc.

Synopsis :

The remote SMTP server is vulnerable to authentication bypass.

Description :

The remote SMTP server did not complain when issued the
command :

MAIL FROM: |testing

This probably means that it is possible to send mail
that will be bounced to a program, which is
a serious threat, since this allows anyone to execute
arbitrary commands on this host.

*** This security hole might be a false positive, since
*** some MTAs will not complain to this test, but instead
*** just drop the message silently

Solution :
