OL 9 must use the invoking user's password for privilege escalation when using sudo.

If the rootpw, targetpw, or runaspw flags are defined and not disabled, by default the operating system will prompt the invoking user for the "root" user password.

Verify that OL 9 is configured to enforce the sudoers security policy to use the invoking user's password for privilege escalation with the following command:

$ sudo egrep -i '(!rootpw|!targetpw|!runaspw)' /etc/sudoers /etc/sudoers.d/* | grep -v '#' /etc/sudoers:Defaults !targetpw /etc/sudoers:Defaults !rootpw /etc/sudoers:Defaults !runaspw

If no results are returned, this is a finding.

If results are returned from more than one file location, this is a finding.

If "Defaults !targetpw" is not defined, this is a finding.

If "Defaults !rootpw" is not defined, this is a finding.

If "Defaults !runaspw" is not defined, this is a finding.

Configure OL 9 to use the invoking user's password for privilege escalation when using sudo.

Define the following in the Defaults section of the /etc/sudoers file or a single configuration file in the /etc/sudoers.d/ directory:

Defaults !targetpw Defaults !rootpw Defaults !runaspw
