Description
Malicious users with removable boot media can gain access to a system configured to use removable media as the boot loader.
ℹ️ Check
Check the servers boot lists for the "normal", "service", "both", or "prevboot" modes by command:
# bootlist -m <mode> -o
Ensure "hdisk{x}" is the only devices listed. If boot devices, such as "cd{x}", "fd{x}", "rmt{x}", or "ent{x}" are used, this is a finding.
✔️ Fix
Configure the system to use a bootloader installed on fixed media, such as:
# bootlist -m normal hdisk0
# bootlist -m service hdisk0
