Vulnerability discussion

USB is a common computer peripheral interface. USB devices may include storage devices that could be used to install malicious software on a system or exfiltrate data.

Check content

If the system needs USB, this vulnerability is not applicable. Check if the directory /proc/bus/usb exists. If the directory /proc/bus/usb exists, this is a finding.

Fix text

Edit the grub bootloader file /boot/grub/menu.lst by appending the "nousb" parameter to the kernel boot line.

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.
