Vulnerability Number

V-273606

Group Title

SRG-NET-000205-RTR-000002

Fix Recommendation

Configure inbound ACLs to block fragmented packets destined to itself.

ICX(config)#interface ethernet 1/1/1
ICX(config-if-e1000-1/1/1)#ip access-group EXT-ACL in logging enable
ICX(config-if-e1000-1/1/1)#ip access-group frag deny

Check Contents

Verify router management interfaces are configured to drop fragmented packets.

Interface ethernet 1/1/1
ip access-group EXT_ACL in logging enable
ip access-group frag deny

If the router is not configured with a receive-path filter to drop all fragmented ICMP packets, this is a finding.

Note: If the platform does not support the receive path filter, verify that all layer 3 interfaces have an ingress ACL to control what packets are allowed to be destined to the router for processing.
