Vulnerability discussion

The finger service provides information about the system's users to network clients. This information could expose information to be used in subsequent attacks.

Check content

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

Fix text

Open a terminal session and use the following command to disable finger. launchctl unload -w /System/Library/LaunchDaemons/finger.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.
