Host header injection

 Hey guys how are you, today we're going to discuss about another vulnerabilitie called host header injection.

As Name implies, we are injecting something malicious in host header.

So without getting further delay let's get started.

What is a Host Header Attack?

It is common practice for the same web server to host several websites or web applications on the same IP address. This why the host header exists. The host header specifies which website or web application should process an incoming HTTP request. The web server uses the value of this header to dispatch the request to the specified website or web application. Each web application hosted on the same IP address is commonly referred to as a virtual host. So what constitutes a host header attack?

What happens if we specify an invalid Host Header? Most web servers are configured to pass the unrecognized host header to the first virtual host in the list. Therefore, it’s possible to send requests with arbitrary host headers to the first virtual host.

How to find this vulnerabilitie?
