ℹ️ Check
Verify the operating system requires users to reauthenticate for privilege escalation. Check the configuration of the "/etc/sudoers" and "/etc/sudoers.d/" files with the following command: # grep -i authenticate /etc/sudoers /etc/sudoers.d/ If any uncommented line is found with a "!authenticate" tag, this is a finding.

✔️ Fix
Configure the operating system to require users to reauthenticate for privilege escalation. Check the configuration of the "/etc/sudoers" file with the following command: # visudo Remove any occurrences of "!authenticate" tags in the file. Check the configuration of the "/etc/sudoers.d/" files with the following command: # grep -i authenticate /etc/sudoers /etc/sudoers.d/ Remove any occurrences of "!authenticate" tags in the file(s).
