Discussion

Without reauthentication, users may access resources or perform tasks for which they do not have authorization. When SLEM 5 provides the capability to change user authenticators, change security roles, or escalate a functional capability, it is critical the user reauthenticate.

Check Content

Verify that SLEM 5 requires reauthentication when changing authenticators, roles, or escalating privileges with the following command:

     > sudo egrep -i '(nopasswd|!authenticate)' /etc/sudoers

If any uncommented lines containing "!authenticate", or "NOPASSWD" are returned and active accounts on the system have valid passwords, this is a finding.

Fix Text

Configure SLEM 5 to remove any occurrence of "NOPASSWD" or "!authenticate" found in the "/etc/sudoers" file. If the system does not use passwords for authentication, the "NOPASSWD" tag may exist in the file.
