Here I am explaining a new and simple way to hack any website with DNN(DotNetNuke). DotNetNuke is an open source platform for building web sites based on Microsoft .NET technology. It is easiest techniques to hack any website coompare than other technique Such as Cross Site Scripting and SQL injection. In this technique we reached the root path for any website and here we can easily upload our own file and can also replace the logo, text, images etc.
Follow these steps to hack any website..
1.  In our first step we check whether the Website is vulnerable or not by using google dorks.  Search following code in google.

inurl:/portals/0

If you can check your desired domain than use below code. Here we can change .com to any desired domain like as .net, .org etc

inurl:/portals/0 site:.com

2.  Now choose any website and copy the url of website without /portals/0 , and paste the below code after it.

Providers/HtmlEditorProviders/Fck/fcklinkgallery.aspx

For ex. the website is http://www.abc.com/portals/0
remove the portals/0 and add the above code. It will become as http://www.abc.com/

3.  If you will get this screen means this website is vulnerable.
