Fix Recommendation

Edit cron script files and modify the umask to 077.

Check Contents

Determine if there are any crontabs by viewing a long listing of the directory. If there are crontabs, examine them to determine what cron jobs exist. Check for any programs specifying an umask.

# ls -lL /var/spool/cron/crontabs
# cat <crontab file>
# grep umask <cron program>

If there are no cron jobs present, this vulnerability is not applicable. If any cron job contains an umask value more permissive than 077, this is a finding.

Severity Override Guidance:
If a cron program sets the umask to 000 or does not restrict the world-writable permission, this becomes a CAT I finding.
