SV-96203r1_rule The macOS system must be configured with automatic actions disabled for blank CDs.

Vulnerability discussion

Applications should not be configured to launch automatically when a disk is inserted. This potentially circumvents anti-virus software and allows malicious users to craft disks that can exploit user applications. Disabling Automatic Actions for blank CDs mitigates this risk.

Check content

If an approved HBSS DCM/DLP solution is installed, this is not applicable. To check if the system has the correct setting for blank CDs in the configuration profile, run the following command: /usr/sbin/system_profiler SPConfigurationProfileDataType | /usr/bin/grep -A 2 'com.apple.digihub.blank.cd.appeared' If this is not defined or "action" is not set to "1", this is a finding.

Fix text

This setting is enforced using the "Custom Policy" configuration profile.

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.
