Vulnerability discussion

Default accounts, such as bin, sys, adm, uucp, daemon, and others, should never have access to the at facility. This would create a possible vulnerability open to intruders or malicious users.

Check content

# more /etc/cron.d/at.allow If default accounts (such as bin, sys, adm, and others) are listed in the at.allow file, this is a finding.

Fix text

Remove the default accounts (such as bin, sys, adm, and others) from the at.allow file.

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.
