Title

The traceroute command must be group-owned by sys, bin, or root. (Cat II impact)

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 possibly leading to system and network compromise.

Check Content

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, or bin, this is a finding.

Fix Text

Change the group-owner of the traceroute command to root. Procedure: # chgrp root /usr/sbin/traceroute
