Discussion

Trust .rhost file means a compromise on one host can allow an attacker to move trivially to other hosts.

Check Content

Check the SSH daemon configuration for allowed ".rhosts" using command: # grep -i IgnoreRhosts /etc/ssh/sshd_config | grep -v '^#' IgnoreRhosts yes If no lines are returned, or the returned "IgnoreRhosts" directive is not set to "yes", this is a finding.

Fix Text

Edit "/etc/ssh/sshd_config" and add or update the "IgnoreRhosts " line as: IgnoreRhosts yes Save the change and restart ssh daemon: # stopsrc -s sshd # startsrc -s sshd
