SV-60979r1_rule Login must not be permitted with empty/null passwords for SSH.

Vulnerability discussion

Permitting login without a password is inherently risky.

Check content

Determine if empty/null passwords are allowed for the SSH service. # grep "^PermitEmptyPasswords" /etc/ssh/sshd_config If the output of this command is not: PermitEmptyPasswords no this is a finding.

Fix text

The root role is required. Modify the sshd_config file # pfedit /etc/ssh/sshd_config Locate the line containing: PermitEmptyPasswords/ Change it to: PermitEmptyPasswords/ no Restart the SSH service. # svcadm restart svc:/network/ssh

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
