SV-27107r1_rule The system must not have accounts configured with blank or null passwords.

Vulnerability discussion

If an account is configured for password authentication but does not have an assigned password, it may be possible to log into the account without authentication. If the root user is configured without a password, the entire system may be compromised. For user accounts not using password authentication, the account must be configured with a password lock value instead of a blank or null value.

Check content

Verify no accounts have blank passwords. # pwdck -n ALL If any account with a blank password is found, this is a finding.

Fix text

Remove or configure a password for any account with a blank password. # passwd # smitty passwd To remove an account with a blank password. # smitty rmuser

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.
