RHEL-06-000529 - The sudo command must require authentication - /etc/sudoers NOPASSWD

Information

The 'sudo' command allows authorized users to run programs (including shells) as other users, system users, and root. The '/etc/sudoers' file is used to configure authorized 'sudo' users as well as the programs they are allowed to run. Some configuration options in the '/etc/sudoers' file allow configured users to run programs without re-authenticating. Use of these configuration options makes it easier for one compromised account to be used to compromise other accounts.

Solution

Update the '/etc/sudoers' or other sudo configuration files to remove or comment out lines utilizing the 'NOPASSWD' and '!authenticate' options.

# visudo
# visudo -f [other sudo configuration file]
