SV-38808r1_rule The traceroute file must not have an extended ACL.

Vulnerability discussion

If an extended ACL exists on the traceroute executable file, it may provide unauthorized users with access to the file. Malicious code could be inserted by an attacker and triggered whenever the traceroute command is executed by authorized users. Additionally, if an unauthorized user is granted executable permissions to the traceroute command, it could be used to gain information about the network topology behind 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 permissions of the /usr/sbin/traceroute file. #aclget /usr/sbin/traceroute Check if extended permissions are disabled. If extended permissions are not disabled, this is a finding.

Fix text

Remove the extended ACL from the traceroute file and disable extended permissions. #acledit /usr/sbin/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.
