Description
SSH trust relationships mean a compromise on one host can allow an attacker to move trivially to other hosts. SSH can emulate the behavior of the obsolete "rsh" command in allowing users to enable insecure access to their accounts via ".rhosts" files.

Check Text (C-258738r933275_chk)

From an ESXi shell, run the following command: # esxcli system ssh server config list -k ignorerhosts or From a PowerCLI command prompt while connected to the ESXi host, run the following commands: $esxcli = Get-EsxCli -v2 $esxcli.system.ssh.server.config.list.invoke() | Where-Object {$_.Key -eq 'ignorerhosts'} Example result: ignorerhosts yes If "ignorerhosts" is not configured to "yes", this is a finding.

Fix Text (F-62387r933274_fix)

From an ESXi shell, run the following command: # esxcli system ssh server config set -k ignorerhosts -v yes or From a PowerCLI command prompt while connected to the ESXi host, run the following commands: $esxcli = Get-EsxCli -v2 $arguments = $esxcli.system.ssh.server.config.set.CreateArgs() $arguments.keyword = 'ignorerhosts' $arguments.value = 'yes' $esxcli.system.ssh.server.config.set.Invoke($arguments)
