Title

The traceroute command owner must be root. (Cat II impact)

Discussion

If the traceroute command owner has not been set to root, an unauthorized user could use this command to obtain knowledge of the network topology inside 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

# ls -lL /usr/sbin/traceroute If the traceroute command is not owned by root, this is a finding.

Fix Text

Change the owner of the traceroute command to root. Example procedure: # chown root /usr/sbin/traceroute
