Host must deny shell access for the dcui account

СреднийУровень 1Автоматическаяvmware

Описание

The dcui account, utilized for process isolation for the Direct Console User Interface (DCUI), possesses shell access which, when deactivated, minimizes the attack surface. This action is a proactive measure to enhance system security. The audit runs esxcli system account list and requires Shell Access false for dcui. Runs in the ESXi Shell (busybox sh) as root.

Как проверяется

Метод проверки: Команда оболочки

shell

out=$(esxcli system account list 2>/dev/null) || exit 1
v=$(printf '%s\n' "$out" | awk '$1=="dcui" {print tolower($NF); exit}')
case "$v" in false) echo compliant ;; '') echo 'dcui not listed (or no Shell Access column on this build)'; exit 1 ;; *) echo 'dcui shell access: '"$v" ;; esac

Ожидаемый вывод: compliant

Как исправляется

Метод исправления: Рекомендация или патч инфраструктуры

Configure the dcui service account to have no shell access using the supported ESXi account-management mechanism for the installed build, and verify that the account cannot establish an interactive shell. Note: It is advised not to manually edit /etc/passwd unless directed by Broadcom support.
