SV-26171r1_rule All NFS-exported system files and system directories must be group-owned by root, bin, sys, or system.

Vulnerability discussion

Failure to give group ownership of sensitive files or directories to root provides the members of the owning group with the potential to access sensitive information or change system configuration which could weaken the system's security posture.

Check content

Determine if the NFS exported directories on the system are group-owned by root. If any are not, this is a finding.

Fix text

Change the group owner of NFS exported directories to root.

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.
