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

List the exports. # cat /etc/dfs/dfstab OR # more /etc/dfs/sharetab For each export, check the ownership information. # ls -ldL If the directory is not group-owned by root, sys, or bin this is a finding.

Fix text

Change the group owner of the export directory. # chgrp 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.
