Mastering Modern Web Penetration Testing

By: Prakhar Prasad, Rafay Baloch

Overview of this book

Web penetration testing is a growing, fast-moving, and absolutely critical field in information security. This book executes modern web application attacks and utilises cutting-edge hacking techniques with an enhanced knowledge of web application security. We will cover web hacking techniques so you can explore the attack vectors during penetration tests. The book encompasses the latest technologies such as OAuth 2.0, Web API testing methodologies and XML vectors used by hackers. Some lesser discussed attack vectors such as RPO (relative path overwrite), DOM clobbering, PHP Object Injection and etc. has been covered in this book. We'll explain various old school techniques in depth such as XSS, CSRF, SQL Injection through the ever-dependable SQLMap and reconnaissance. Websites nowadays provide APIs to allow integration with third party applications, thereby exposing a lot of attack surface, we cover testing of these APIs using real-life examples. This pragmatic guide will be a great benefit and will help you prepare fully secure applications.

Receiving grants


OAuth 2.0 basically allows a third party website to access a limited or selective set of user information on a particular website. There are different kinds of authorization flows, two common ones of which are as follows:

  • Authorization grant

  • Implicit grant

We'll have a look at them in the following sub-sections.

Authorization grant

An authorization grant consists of an authorization link, which looks like the following:

https://www.example.com/oauth/authorize?response_type=code&client_id=CLIENT_ID&redirect_uri=CALLBACK_URL&scope=read

Let's break down the different components here:

  • response_type: When set to code, the OAuth authorization server expects the grant to be of authorization grant type

  • client_id: This is the client ID/app ID of the application

  • redirect_uri: This contains a URL in percent-encoded form, and after the initial flow is complete, the authorization server redirects the flow to the specified URL

  • scope: This refers to the level of access needed; this...
