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 insecure deserialization


Deserialization is the process of passing some type of data to other data, to be managed by the application, for example, passing a JSON format request that is parsed and managed as XML by the application. Also, there are deserialization vulnerabilities where the technology used in the development is involved. These vulnerabilities pass resources of a certain type to binary objects.

To understand the vulnerability, review the next snippet of code, published in the CVE.2011-2092:

[RemoteClass(alias="javax.swing.JFrame")] 
public class JFrame { 
   public var title:String = "Gotcha!"; 
   public var defaultCloseOperation:int = 3; 
   public var visible:Boolean = true; 
} 

This code is the class definition of a data type called JFrame. In the next snippet of code, we can see how it is used:

InputStream is = request.getInputStream(); 
ObjectInputStream ois = new ObjectInputStream(is); 
AcmeObject acme = (AcmeObject)ois.readObject(); 

The issue is that any kind of...
