Title
The system must not allow accounts configured with blank or null passwords. (Cat I impact)
Discussion
If an account has an empty password, anyone could log in and run commands with the privileges of that account. Accounts with empty passwords should never be used in operational environments.
Check Content
To verify that null passwords cannot be used, run the following command: # grep nullok /etc/pam.d/system-auth /etc/pam.d/password-auth If this produces any output, it may be possible to log on to accounts with empty passwords. If null passwords can be used, this is a finding.
Fix Text
If an account is configured for password authentication but does not have an assigned password, it may be possible to log on to the account without authentication. Remove any instances of the "nullok" option in "/etc/pam.d/system-auth" and "/etc/pam.d/password-auth" to prevent logons with empty passwords.
