Permissions necessary for CGI to create files

I would like to have a perl cgi script that will create a text file.  I found that my script can do this easily if the document root has full permissions (chmod 777) but I don't think that this is a good idea to leave full permission open, right? This is the basic structure of my web:

The absolute path is /home/sites/site1/users/~user1/

The web document root is /~user1/web/

location of cgi-bin is inside of /web like this
/~user1/web/cgi-bin/

My question is this, what should the permissions be for the document root and the cgi-bin to allow my cgi script to be able to create files and read files. I am using the HTTP_REFERRER env var to check and make sure the cgi-script can only be run from my site.

Thanks for your help

cgi-bin needs read/execute rights

root needs write/read rights

never give write and execute writes to the same dir as if somebody uploads an exe/script they can execute it a trash the server. your cgi-bin dir should use another dir for writing files, in your case use your root
