Vulnerability discussion

Malicious users with removable boot media can gain access to a system configured to use removable media as the boot loader.

Check content

Check the servers boot lists for the normal, service, both, or prevboot modes. # bootlist -m -o Ensure hdisk{x} is the only devices listed. If boot devices, such as cd{x}, fd{x}. rmt{x}, ent{x} are used, this is a finding.

Fix text

Configure the system to use a bootloader installed on fixed media. # bootlist -m normal hdisk0 # bootlist -m service hdisk0

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.
