The Content-Type header is used to indicate the media type of the resources. The content-type header is used to send a client, what to expect from the server.

There are many web applications that didn’t implement a Content-Type header value. This value informs the browser what kind of data to expect. If this header is missing, the browser may incorrectly handle the data. This could lead to security problems like a man in the middle attacks.


The following code is an example of a content type header.

        Content-Type: text/html; charset=utf-8
        Content-Type: multipart/form-data; boundary=something



The impact include:-

  • Man in the middle attacks
