Description
If cron files and folders are accessible to unauthorized users, malicious jobs may be created.
ℹ️ Check
At the command line, run the following command:
# find /etc/cron.d/ /etc/cron.daily/ /etc/cron.hourly/ /etc/cron.monthly/ /etc/cron.weekly/ -xdev -type f -a '(' -perm -022 -o -not -user root ')' -exec ls -ld {} \;
If any files are returned, this is a finding.
✔️ Fix
At the command line, run the following commands for each returned file:
# chmod 644 <file>
# chown root <file>
