Vulnerability Discussion

If the "sudoers" file is not configured correctly, any user defined on the system can initiate privileged actions on the target system.

Check

Remove the following entries from the /etc/sudoers file or configuration file under /etc/sudoers.d/:

ALL ALL=(ALL) ALL
ALL ALL=(ALL:ALL) ALL

Fix

Verify RHEL 9 restricts privilege elevation to authorized personnel with the following command:

$ sudo sh -c 'grep -iw ALL /etc/sudoers /etc/sudoers.d/*'

If the either of the following entries are returned, this is a finding:
ALL ALL=(ALL) ALL
ALL ALL=(ALL:ALL) ALL
