Vulnerability discussion

The Screen Sharing feature allows remote users to view or control the desktop of the current user. A malicious user can take advantage of Screen Sharing to gain full access to the system remotely, either with stolen credentials or by guessing the username and password. Disabling Screen Sharing mitigates this risk.

Check content

To check if the 'screen sharing' service is disabled, use the following command: sudo launchctl print-disabled system | grep com.apple.screensharing If the results do not show the following: "com.apple.screensharing" => true this is a finding.

Fix text

To disable the 'screen sharing' service, run the following command: sudo launchctl disable system/com.apple.screensharing The system may need to be restarted for the update to take effect.

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.
