The Photon operating system must disable the debug-shell service.

Rule version PHTN-30-000076 · STIG v1 · 2026-08-31

Discussion

The debug-shell service is intended to diagnose systemd-related boot issues with various "systemctl" commands. Once enabled and following a system reboot, the root shell will be available on tty9. This service must remain disabled until and unless otherwise directed by VMware support.

Check

At the command line, run the following command:

# systemctl status debug-shell.service|grep -E --color=always disabled

If the debug-shell service is not disabled, this is a finding.

Fix

At the command line, run the following commands:

# systemctl stop debug-shell.service
# systemctl disable debug-shell.service

Reboot for changes to take effect.
