When operating systems provide the capability to escalate a functional capability, it is critical the user reauthenticate.

At the command line, run the following commands to verify users with a set password are not allowed to sudo without reauthentication:
# grep -ihs nopasswd /etc/sudoers /etc/sudoers.d/*|grep -vE '(^#|^%)'
# awk -F: '($2 != "x" && $2 != "!") {print $1}' /etc/shadowIf any account listed in the first output is also listed in the second output and is not documented, this is a finding.
Check the configuration of the "/etc/sudoers" and "/etc/sudoers.d/*" files with the following command:
# visudo
OR
# visudo -f /etc/sudoers.d/<file name>
Remove any occurrences of "NOPASSWD" tags associated with user accounts with a password hash.
