Host must deny shell access for the dcui account

中レベル 1自動vmware

説明

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.

修正方法

修正方法: ガイダンスまたは IaC パッチ

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.
