Title

The SUSE operating system must restrict privilege elevation to authorized personnel. (Cat II impact)

Discussion

The sudo command allows a user to execute programs with elevated (administrator) privileges. It prompts the user for their password and confirms your request to execute a command by checking a file, called sudoers. If the "sudoers" file is not configured correctly, any user defined on the system can initiate privileged actions on the target system.

Check Content

Verify the "sudoers" file restricts sudo access to authorized personnel. > sudo 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

Fix Text

Remove the following entries from the sudoers file: ALL ALL=(ALL) ALL ALL ALL=(ALL:ALL) ALL
