Vulnerability discussion

Without providing this capability, an account may be created without a password. Nonrepudiation cannot be guaranteed once an account is created if a user is not forced to change the temporary password upon initial logon.Temporary passwords are typically used to allow access when new accounts are created or passwords are changed. It is common practice for administrators to create temporary passwords for user accounts that allow the users to log on, yet force them to change the password once they have successfully authenticated.

Check content

Verify that a policy exists that ensures when a user is created, it is creating using a method that forces a user to change their password upon their next login. If a policy does not exist, then this is a finding.

Fix text

Configure the SUSE operating system to allow the use of a temporary password for system logons with an immediate change to a permanent password. Using one of the acceptable methods listed below, force a user to change their password on their next logon by replacing "[UserName]" in the one of the following commands: # chage -d 0 [UserName] # passwd -e [UserName]

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.
