HTTP headers. HTTP headers let the client and the server pass additional information with an HTTP request or response. An HTTP header consists of its case-insensitive name followed by a colon (: ), then by its value. Whitespace before the value is ignored host=<host> The Host request header field as received by the proxy. proto=<http|https> Indicates which protocol was used to make the request (typically http or https) HTTP Headers. HTTP message headers are used to describe a resource, or the behavior of the server or the client. Custom proprietary headers can be added using the X- prefix; others in an IANA registry, whose original content was defined in RFC 4229. IANA also maintains a registry of proposed new HTTP message headers O cabeçalho de solicitação de Host especifica o nome de domínio do servidor (para hospedagem virtual), e (opcionalmente) o número da porta TCP no qual o servidor está escutando.

The most practical solution for an up-to-date (IIS 10 +) setup is using removeServerHeader in the web.config HTTP 1.1 requests often include a Host: header, which contains the hostname from the client request. This is because a server may use a single IP address or interface to accept requests for multiple DNS hostnames. The Host: header identifies the server requested by the client The host header name (www.gafvert.info in the example) and IP (192.168..1 in the example) can be omitted. To determine which website should handle a request, IIS checks if there is a website configured to listen on the IP address and port number the request came in on, and which also matches the host header value sent in the HTTP message How to exploit the HTTP Host header. Once you have identified that you can pass arbitrary hostnames to the target application, you can start to look for ways to exploit it. In this section, we'll provide some examples of common HTTP Host header attacks that you may be able to construct An HTTP/1.1 proxy MUST ensure that any request message it forwards does contain an appropriate Host header field that identifies the service being requested by the proxy. All Internet-based HTTP/1.1 servers MUST respond with a 400 (Bad Request) status code to any HTTP/1.1 request message which lacks a Host header field
