By: Sunny Wear

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 for Insecure Direct Object Reference (IDOR)

Allowing unauthorized direct access to files or resources on a system based on user-supplied input is known as Insecure Direct Object Reference (IDOR). This vulnerability allows the bypassing of authorization checks placed on such files or resources. IDOR is a result of unchecked user supplied input to retrieve an object without performing authorization checks in the application code.

Getting ready

Using OWASP Mutillidae II as our target application, let's manipulate the value of the phpfile parameter to determine whether we can make a call to a direct object reference on the system, such as /etc/passwd file.
