Your mission is to exploit this code, which has obviously an LFI vulnerability:

GeSHi`ed PHP code

1 2	$filename = 'pages/'.(isset($_GET["file"])?$_GET["file"]:"welcome").'.html'; include $filename;

There is a lot of important stuff in ../solution.php, so please include and execute this file for us.

Here are a few examples of the script in action (in the box below):
index.php?file=welcome
index.php?file=news
index.php?file=forums

For debugging purposes, you may look at the whole source again, also as highlighted version.

This is the news page.

Dude, you got rooted by ZeroCool xD

Thanks go out to minus for his alpha testing, great thoughts and motivation!
