Bug description:  CGI php.exe allows for ANY file to be read from the server

I'm using Apache 1.3.19 on Windows 2000, with PHP 4.0.4pl1 running as a CGI executable.

Occasionaly whilst testing on localhost, Apache will set the current address as, for 
example:

http://127.0.0.1/php/php.exe?/path/to/index.php

This can be modified, to read ANY file from the server.

http://127.0.0.1/php/php.exe?c:\windows\win.ini

would, for example, print out in plaintext the contents of that file on a Win9x system.

IMO, this represents an enormous potential security problem, although is it dependant 
on the attacker knowing the path to the php.exe executable, and the filename he wishes 
to retrive.

This works on my Windows 2000 and Windows 98SE machines, both of which have PHP 
running as an executable.
The initial setup instructions come from http://www.phpbuilder.com/, which set PHP to 
be installed as c:\php\php.exe by default.
