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.

Unrestricted file upload – bypassing weak validation

Many applications allow for files to be uploaded for various reasons. Business logic on the server-side must include checking for acceptable files; this is known as whitelisting. If such checks are weak or only address one aspect of file attributes (for example, file extensions only), attackers can exploit these weaknesses and upload unexpected file types that may be executable on the server.

Getting ready

Using the Damn Vulnerable Web Application (DVWA)application and Burp, we will exploit a business logic design flaw in the file upload page.
