SMTP: MAIL FROM "|"
This signature detects attempts to send shell commands through a SMTP e-mail message by exploiting the pipe passthrough vulnerability. Attackers can use the invalid "mail from |" as the return e-mail address to cause Sendmail to reroute data to another program.
Extended Description
A remote attacker could gain unauthorized access to a vulnerable system.
