The system must not accept source-routed IPv6 packets.


Overview

Finding ID Version Rule ID IA Controls Severity
V-22554 GEN007940 SV-42323r1_rule ECSC-1 Medium
Description
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 handling of source-routed traffic destined to the system itself, not to traffic forwarded by the system to another, such as when IPv6 forwarding is enabled and the system is functioning as a router.
