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 XSS vulnerabilities


XSS has three different types, but all of them have one thing in common—they derive from the input validation error to manage characters that are used to inject JavaScript code or HTML tags. So, we can use some inputs as shown in the following screenshot (which is a cheat sheet from the OWASP project), and add to the Intruder tool as payload:

The way to detect XSS vulnerabilities is to find these codes without encoding or modifications in the responded HTML or that we did not get an error after injecting the testing strings.

To add the cheat sheet, use a similar process to adding the payload list to Intruder. Open the Intruder tool, click on the Payloads tab, and then select the Load button. Finally, mark all the parameters that you think are vulnerable, then click on Start attack, as shown in the following screenshot:

In the preceding screenshot, we can see how all the strings were launched by Intruder...
