SV-72859r1_rule The system must not have the finger service active.

Vulnerability discussion

The finger service has had several security vulnerabilities in the past and is not a necessary service. It is disabled by default; enabling it would increase the attack surface of the system.

Check content

To check if the finger service has been disabled, run the following command: sudo /usr/libexec/PlistBuddy -c 'print com.apple.fingerd: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 ensure that the finger service is disabled, run the following command: sudo defaults write /private/var/db/launchd.db/com.apple.launchd/overrides.plist 'com.apple.fingerd' -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.
