SV-63179r1_rule The system must have USB Mass Storage disabled unless needed.

Vulnerability discussion

USB is a common computer peripheral interface. USB devices may include storage devices with the potential to install malicious software on a system or exfiltrate data

Check content

If the system needs USB storage, this vulnerability is not applicable. Check if usb-storage is prevented from loading. # grep 'install usb-storage /bin/true' /etc/modprobe.conf /etc/modprobe.d/* If no results are returned, this is a finding.

Fix text

Prevent the usb-storage module from loading. # echo 'install usb-storage /bin/true' >> /etc/modprobe.conf

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.
