GEN003600 - The system must not forward IPv4 source-routed packets.

Information

Source-routed packets allow the source of the packet to suggest routers forward the packet along a different path than configured on the router, which can be used to bypass network security measures. This requirement applies only to the forwarding of source-routed traffic, such as when IPv4 forwarding is enabled and the system is functioning as a router.

Solution

# /usr/sbin/no -po 'ipsrcrouteforward=0'
