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 SSH daemon configuration and add or edit the 'RhostsRSAAuthentication' setting value to 'no'.

Restart the SSH daemon.
# /sbin/service sshd restart
