Check: GEN003600

VMware ESX 3 Server: GEN003600 (in version v1 r2)

Title

The system must not forward IPv4 source-routed packets. (Cat II impact)

Discussion

Source-routed packets allow the source of the packet to suggest that 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.

Check Content

If the system is configured to forward source-routed packets, this is a finding.

Fix Text

Configure the system to not forward source-routed packets.
