Technical details
This is a configuration-based vulnerability where a host or router responds to ICMP Time Exceeded or unreachable messages, or UDP probes, allowing the 'traceroute' utility to function from any source. It is classified as a configuration issue rather than a software flaw. An attacker can use this to discover the hop-by-hop path to a destination and identify internal network topology. Mitigation typically involves configuring firewalls or ACLs to rate-limit or drop ICMP TTL-expired messages and specific UDP port ranges used by traceroute.
