Vulnerability Discussion

Service configuration files enable or disable features of their respective services that if configured incorrectly can lead to insecure and vulnerable configurations. Therefore, service configuration files should have the correct access rights to prevent unauthorized changes.

Check

Verify the permissions of the cron directories with the following command:

$ find /etc/cron* -type d | xargs stat -c "%#a %n"

0700 /etc/cron.d
0700 /etc/cron.daily
0700 /etc/cron.hourly
0700 /etc/cron.monthly
0700 /etc/cron.weekly

If any cron configuration directory is more permissive than "700", this is a finding.

Fix

Configure any AlmaLinux OS 9 cron configuration directory with a mode more permissive than "0700" as follows:

chmod 0700 [cron configuration directory]
