Vulnerability discussion

Non-local maintenance and diagnostic activities are those activities conducted by individuals communicating through a network, either an external network (e.g., the Internet) or an internal network. To protect the integrity and confidentiality of non-local maintenance and diagnostics, all packets associated with these sessions must be encrypted.

Check content

The service "telnet" should be disabled, to check the status of the service, run the following command: sudo /usr/libexec/PlistBuddy -c "print com.apple.telnetd:Disabled" /var/db/launchd.db/com.apple.launchd/overrides.plist If the returned value isn't "true" or doesn't exist, this is a finding.

Fix text

To set the "telnet" service to disabled, run the following command: sudo defaults write /private/var/db/launchd.db/com.apple.launchd/overrides.plist "com.apple.telnetd" -dict Disabled -bool true

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.
