Discussion

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. Satisfies: SRG-OS-000373-GPOS-00156, SRG-OS-000373-GPOS-00157, SRG-OS-000373-GPOS-00158

Check Content

Verify the sudoers security policy is configured to use the invoking user's password for privilege escalation using the following command:

$ sudo egrep -ir '(!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.

Fix Text

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
