SV-63487r1_rule The traceroute command owner must be root.

Vulnerability 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 potentially leading to system and network compromise.

Check content

# ls -lL /bin/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: # chown root /bin/traceroute

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
