Vulnerability discussion

If there are excessive file permissions for the cron.deny file, sensitive information could be viewed or edited by unauthorized users.

Check content

#aclget /var/adm/cron/cron.deny Verify if extended permissions are disabled. If extended permissions are not disabled, this is a finding.

Fix text

Remove the extended ACL from the cron.deny file and disable extended permissions. #acledit /var/adm/cron/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.
