This script is Copyright (C) 2011-2013 Tenable Network Security, Inc.


Synopsis :

The remote router allows traffic redirection.

Description :

According to its self-reported version number, the remote Juniper
router has a vulnerable Extended DHCP Relay Agent. Any
interface which has the Extended DHCP Relay Agent enabled
intercepts unicast DHCP reply packets. A remote attacker could
exploit this by acting as a malicious DHCP server, sending
specially crafted unicast DHCP reply packets through the router.
This could result in traffic being redirected.
