Vulnerability discussion

If file permissions for cron.deny are more permissive than 0700, sensitive information could be viewed or edited by unauthorized users.

Check content

Check the permissions of the file. # ls -lL /etc/cron.d/cron.deny If the permissions include a "+", the file has an extended ACL and this is a finding.

Fix text

Remove the extended ACL from the file. # chmod A- /etc/cron.d/cron.deny

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.
