VMware ESXi
TMA-ESXI9-3.10
Host must not suppress warnings that the shell is enabled
Descripción
Having warnings for enabled SSH or ESXi Shell provides insight into potential security risks. Disabling such warnings can mask ongoing attacks. The parameter governing this behavior is UserVars.SuppressShellWarning with a recommended value of 0. The audit reads UserVars.SuppressShellWarning with esxcli and requires 0. Runs in the ESXi Shell (busybox sh) as root.
