Fix Recommendation

Edit /etc/ssh/ssh_config and add or edit the "Ciphers" line. Only include ciphers that start with "3des" or "aes" and do not contain "cbc". For the list of available ciphers for the particular version of your software, consult the ssh_config manpage.

Check Contents

Check the SSH client configuration for allowed ciphers.
# grep -i ciphers /etc/ssh/ssh_config | grep -v '^#'
If no lines are returned, or the returned ciphers list contains any cipher ending with cbc, this is a finding.
