Discussion

Without reauthentication, users may access resources or perform tasks for which they do not have authorization.

Check Content

Verify Amazon Linux 2023 requires users to reauthenticate for privilege escalation. 

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

$ sudo grep -ir '!authenticate' /etc/sudoers /etc/sudoers.d/

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

Fix Text

Configure Amazon Linux 2023 to not allow users to execute privileged actions without authenticating.

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

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