Juniper Junos Extended DHCP Relay Agent Traffic Redirection (PSN-2011-07-300)

low Nessus Plugin ID 55934


The remote router allows traffic redirection.


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.
