It is really not a good idea to run your CGI scripts as root. If someone comprosmises your web server they have won instant access to everything. If someone finds a bug in your program they can exploit it for root access. If your program misbehaves, it can damage anything. There's a reason most things don't run as root, and a reason webservers in particular get very little access to anything -- anyone in the world can cause a request to happen, and can inject any data they want with ease.

You could perhaps use sudo to allow your webserver to run very specific things as root, so you could do system("sudo /path/to/script.sh"); Don't give it a blank cheque. Only let it run very specific scripts, and write those scripts very carefully.
