Description
If the system does not require valid root authentication before it boots into single-user or maintenance mode, anyone who invokes single-user or maintenance mode is granted privileged access to all files on the system.

ℹ️ Check
Verify the operating system must require authentication upon booting into single-user and maintenance modes. Check that the operating system requires authentication upon booting into single-user mode with the following command: # grep -i execstart /usr/lib/systemd/system/rescue.service \| grep -i sulogin ExecStart=-/bin/sh -c "/usr/sbin/sulogin; /usr/bin/systemctl --fail --no-block default" If "ExecStart" does not have "/usr/sbin/sulogin" as an option, this is a finding.

ℹ️ Check

Verify the operating system must require authentication upon booting into single-user and maintenance modes. Check that the operating system requires authentication upon booting into single-user mode with the following command: # grep -i execstart /usr/lib/systemd/system/rescue.service | grep -i sulogin ExecStart=-/bin/sh -c "/usr/sbin/sulogin; /usr/bin/systemctl --fail --no-block default" If "ExecStart" does not have "/usr/sbin/sulogin" as an option, this is a finding.

✔️ Fix
Configure the operating system to require authentication upon booting into single-user and maintenance modes. Add or modify the "ExecStart" line in "/usr/lib/systemd/system/rescue.service" to include "/usr/sbin/sulogin": ExecStart=-/bin/sh -c "/usr/sbin/sulogin; /usr/bin/systemctl --fail --no-block default"
