Description

The host is configured to honor IP source routing options. Source routing is a feature of the IP protocol which allows the sender of a packet to specify which route the packet should take on the way to its destination (and on the way back). Source routing was originally designed to be used when a host did not have proper default routes in its routing table. However, source routing is rarely used for legitimate purposes nowadays. Attackers can abuse source routing to bypass firewalls or to map your network.
