Discussion

If the group owner of the traceroute command has not been set to a system group, unauthorized users could have access to the command and use it to gain information regarding a network's topology inside of the firewall. This information may allow an attacker to determine trusted routers and other network information potentially leading to system and network compromise.

Check the group ownership of the traceroute file.

Procedure:
# ls -lL /usr/sbin/traceroute
If the traceroute command is not group-owned by root, sys, bin, or system, this is a finding.
