SLEM 5 must restrict privilege elevation to authorized personnel.

The sudo command allows a user to execute programs with elevated (administrator) privileges. It prompts the user for their password and confirms the 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.

Verify the "sudoers" file restricts sudo access to authorized personnel with the following command:

     > sudo grep -iw 'ALL' /etc/sudoers /etc/sudoers.d/*
     root ALL=(ALL) ALL

If "ALL ALL=(ALL) ALL" or "ALL ALL=(ALL:ALL) ALL" entries are returned, this is a finding.

Remove the following entries from the "/etc/sudoers" file:

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