777 permission security issues

Does anyone know of a website that explains why you would not want to set all your file and folder permissions to 777.

I know in rare cases a folder might need to be @ 777 or maybe a file that needs to be written to but I need to show a client that EVERY file and folder (in PHPBB) does not need to be changed to 777... The default 644 and 755 is just fine.

I have tried to explain it but I would like have some type of reference to back up my information with.


Thanks In Advance.
