SV-60907r1_rule The root account must be the only account with GID of 0.

Vulnerability discussion

All accounts with a GID of 0 have root group privileges and must be limited to the group account only.

Check content

Identify any users with GID of 0. # awk -F: '$4 == 0' /etc/passwd # awk -F: '$3 == 0' /etc/group Confirm the only account with a group id of 0 is root. If the root account is not the only account with GID of 0, this is a finding.

Fix text

The root role is required. Change the default GID of non-root accounts to a valid GID other than 0.

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.
