Vulnerability discussion

The telnet daemon provides a typically unencrypted remote access service which does not provide for the confidentiality and integrity of user passwords or the remote session. If a privileged user were to log on using this service, the privileged user password could be compromised.

Check content

Open a terminal session and enter the following command to verify telnet is disabled. defaults read /var/db/launchd.db/com.apple.launchd/overrides com.apple.telnetd If a 1 is not returned, this is a finding.

Fix text

Open a terminal session and use the following command to disable telnet. launchctl unload -w /System/Library/LaunchDaemons/telnet.plist NOTE: This command is being run to adjust the overrides file; unloading errors are normal, repeat the check to verify.

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.
