Check: ESXI-67-000013
VMware vSphere 6.7 ESXi STIG:
ESXI-67-000013
(in versions v1 r3 through v1 r1)
Title
The ESXi host SSH daemon must not allow host-based authentication. (Cat II impact)
Discussion
SSH trust relationships mean a compromise on one host can allow an attacker to move trivially to other hosts. SSH's cryptographic host-based authentication is more secure than ".rhosts" authentication, since hosts are cryptographically authenticated. However, it is not recommended that hosts unilaterally trust one another, even within an organization.
Check Content
From an SSH session connected to the ESXi host, or from the ESXi shell, run the following command: # grep -i "^HostbasedAuthentication" /etc/ssh/sshd_config If there is no output or the output is not exactly "HostbasedAuthentication no", this is a finding.
Fix Text
From an SSH session connected to the ESXi host, or from the ESXi shell, add or correct the following line in "/etc/ssh/sshd_config": Add or correct the following line in "/etc/ssh/sshd_config": HostbasedAuthentication no
