Vulnerability discussion

A cron.allow file that is readable and/or writable by other than root could allow potential intruders and malicious users to use the file contents to help discern information, such as who is allowed to execute cron programs, which could be harmful to overall system and network security.

Check content

Check mode of the cron.allow file. Procedure: # ls -lL /var/adm/cron/cron.allow If the file has a mode more permissive than 0600, this is a finding.

Fix text

Change the mode of the cron.allow file to 0600. Procedure: # chmod 0600 /var/adm/cron/cron.allow

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.
