Hands-On Application Penetration Testing with Burp Suite

By: Carlos A. Lozano, Dhruv Shah, Riyaz Ahemed Walikar

Overview of this book

Burp suite is a set of graphic tools focused towards penetration testing of web applications. Burp suite is widely used for web penetration testing by many security professionals for performing different web-level security tasks. The book starts by setting up the environment to begin an application penetration test. You will be able to configure the client and apply target whitelisting. You will also learn to setup and configure Android and IOS devices to work with Burp Suite. The book will explain how various features of Burp Suite can be used to detect various vulnerabilities as part of an application penetration test. Once detection is completed and the vulnerability is confirmed, you will be able to exploit a detected vulnerability using Burp Suite. The book will also covers advanced concepts like writing extensions and macros for Burp suite. Finally, you will discover various steps that are taken to identify the target, discover weaknesses in the authentication mechanism, and finally break the authentication implementation to gain access to the administrative console of the application. By the end of this book, you will be able to effectively perform end-to-end penetration testing with Burp Suite.

Detecting broken authentication


A broken authentication is a group of issues that affect applications. Some of them are listed here:

  • Weak storage for credentials
  • Predictable login credentials
  • Session IDs exposed in the URL
  • Session IDs susceptible to session fixations attacks
  • Wrong time out implementation
  • The session is not destructed after the logout
  • Sensitive information sent by unprotected channels

We are going to explain how to detect these issues using Burp Suite.

Detecting weak storage for credentials

The information about authentication has a big problem; it is not just stored on the server side, it also needs to be stored on the client side, maybe not in the form of user and password, but in tokens, sessions IDs, or other things that the application uses to track the user and provide access.

Using Burp Suite, it is possible to analyze where this information is stored. For example, it is very common to store the information in cookies, as shown in the following screenshot:

This is an example of...
