Title

The SSH daemon must not allow rhosts RSA authentication. (Cat II impact)

Discussion

If SSH permits rhosts RSA authentication, a user may be able to log in based on the keys of the host originating the request and not any user-specific authentication.

Check Content

Check the SSH daemon configuration for the RhostsRSAAuthentication setting. # grep -i RhostsRSAAuthentication /etc/ssh/sshd_config | grep -v '^#' # grep -i RhostsRSAAuthentication /etc/openssh/sshd_config | grep -v '^#' If the setting is set to yes, this is a finding.

Fix Text

Edit the SSH daemon configuration and change the RhostsRSAAuthentication setting value to no or remove it entirely.
