| Description |
|---|
| 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.

| ℹ️ Check |
|---|
| 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/shadow If any account listed in the first output is also listed in the second output and is not documented, this is a finding. |
| ✔️ Fix |
|---|
| 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. |
