GEN005538 - The SSH daemon must not allow rhosts RSA authentication.

Information

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.

Solution

Edit the /etc/ssh/sshd_config file and remove the RhostsRSAAuthentication setting or change the value of the RhostsRSAAuthentication setting to 'no'.
