Check: ESXI-67-000018
VMware vSphere 6.7 ESXi STIG:
ESXI-67-000018
(in versions v1 r3 through v1 r1)
Title
The ESXi host SSH daemon must not permit GSSAPI authentication. (Cat III impact)
Discussion
GSSAPI authentication is used to provide additional authentication mechanisms to applications. Allowing GSSAPI authentication through SSH exposes the system’s GSSAPI to remote hosts, increasing the attack surface of the system.
Check Content
From an SSH session connected to the ESXi host, or from the ESXi shell, run the following command: # grep -i "^GSSAPIAuthentication" /etc/ssh/sshd_config If there is no output or the output is not exactly "GSSAPIAuthentication 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": GSSAPIAuthentication no
