Overview of this book

Burp Suite is a Java-based platform for testing the security of your web applications, and has been adopted widely by professional enterprise testers. The Burp Suite Cookbook contains recipes to tackle challenges in determining and exploring vulnerabilities in web applications. You will learn how to uncover security flaws with various test cases for complex environments. After you have configured Burp for your environment, you will use Burp tools such as Spider, Scanner, Intruder, Repeater, and Decoder, among others, to resolve specific problems faced by pentesters. You will also explore working with various modes of Burp and then perform operations on the web. Toward the end, you will cover recipes that target specific test scenarios and resolve them using best practices. By the end of the book, you will be up and running with deploying Burp for securing web applications.

Testing CORS

An application that implements HTML5 CORS means the application will share browser information with another domain that resides at a different origin. By design, browser protections prevent external scripts from accessing information in the browser. This protection is known as Same-Origin Policy (SOP). However, CORS is a means of bypassing SOP, permissively. If an application wants to share browser information with a completely different domain, it may do so with properly-configured CORS headers.

Web-penetration testers must ensure applications that handle AJAX calls (for example, HTML5) do not have misconfigured CORS headers. Let's see how Burp can help us identify such misconfigurations.
