Discussion

Without reauthentication, users may access resources or perform tasks for which they do not have authorization. When operating systems provide the capability to escalate a functional capability, it is critical the user reauthenticate.

Check Procedure

Verify the operating system is not configured to bypass password requirements for privilege escalation with the following command:

$ sudo grep pam_succeed_if /etc/pam.d/sudo 

If any occurrences of "pam_succeed_if" are returned, this is a finding.

Fix Action

Configure the operating system to require users to supply a password for privilege escalation.

Remove any occurrences of " pam_succeed_if " in the  "/etc/pam.d/sudo" file.
