Discussion

Without re-authentication, 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 re-authenticate.

Check Content

Verify that "/etc/sudoers" has no occurrences of "!authenticate" with the following command:

$ sudo egrep -iR '!authenticate' /etc/sudoers /etc/sudoers.d/

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

Fix Text

Configure AlmaLinux OS 9 to not allow users to execute privileged actions without authenticating.

Remove any occurrence of "!authenticate" found in the "/etc/sudoers" file or files in the "/etc/sudoers.d" directory with the following command:

$ sed -i '/\!authenticate/ s/^/# /g' /etc/sudoers /etc/sudoers.d/*
