SV-26349r1_rule The system must restrict the ability to switch to the root user to members of a defined group.

Vulnerability discussion

Configuring a supplemental group for users permitted to switch to the root user prevents unauthorized users from accessing the root account, even with knowledge of the root credentials.

Check content

Check /etc/default/security for the SU_ROOT_GROUP setting. # grep SU_ROOT_GROUP /etc/default/security Unless this setting is present, configured, and not commented out, this is a finding.

Fix text

Edit /etc/default/security and uncomment, set, or add the SU_ROOT_GROUP setting with a value of wheel or equivalent. If necessary, create a wheel group and add administrative users to the group.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
