Rik,
Ive sent you an email to the hotmail address luihei...
just to help me clear up a few details. Thanks for the above details.
I should make it clear to anyone interested that the type of exploit
we're talking about does NOT involve saving php code with a jpg
extension and then calling it in a browser:
<?php system('echo hello > hello.htm'); ?>
saved as hello.jpg, and then called using
htpp://server.com/hello.jpg
now that wouldn't usualy work unless you've asked your server to parse
jpgs looking for php code, which is why its a bad idea in general.
The type of attack that usually DOES work on a windows box is to embed
php code inside the binary header of a jpg, usually using a tool to do
it. Even if the server is set up to only parse .php files, it will
still execute the embedded php code inside a jpg.
