Description
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.
