SV-27342r1_rule Cron and crontab directories must have mode 0755 or less permissive.

Vulnerability discussion

To protect the integrity of scheduled system jobs and to prevent malicious modification to these jobs, crontab files must be secured.

Check content

Check the mode of the crontab directory. # ls -ld /var/spool/cron/crontabs If the mode of the crontab directory is more permissive than 0755, this is a finding.

Fix text

Change the mode of the crontab directory. # chmod 0755 /var/spool/cron/crontabs

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.
