The ESXi host Secure Shell (SSH) daemon must ignore ".rhosts" files.
An XCCDF Rule
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.
