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

On HP-UX systems with USB ports, the kernel module "usbd" is installed with the operating system. The "usbd" module enables and currently supports the use of a keyboard, a mouse and an optical drive. # /stand/system | grep -i usb # ioscan -fnC usb Ask the SA if the system requires USB mass storage. If the system requires the use of USB mass storage, this is not applicable. If the kernel module "usbd" is installed and the system does not require usb mass storage, this is a finding.

Fix text

If usb mass storage is not required and the system does not use the system's usb interface for keyboard/mouse input, remove the "usbd" module from the kernel, remake the kernel and reboot the system. Document the change(s). # smh

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.
