Overview of this book

Web applications are the front door to most organizations, exposing them to attacks that may disclose personal information, execute fraudulent transactions, or compromise ordinary users. This practical book has been completely updated and revised to discuss the latest step-by-step techniques for attacking and defending the range of ever-evolving web applications. Youíll explore the various new technologies employed in web applications that have appeared since the first edition and review the new attack techniques that have been developed, particularly in relation to the client side. The book starts with the current state of web application security and the trends that indicate how it is likely to evolve soon. Youíll examine the core security problem affecting web applications and the defence mechanisms that applications implement to address this problem, and youíll also explore the key technologies used in todayís web application. Next, youíll carry out tasks for breaking into web applications and for executing a comprehensive attack. As you progress, youíll learn to find vulnerabilities in an application's source code and review the tools that can help when you hack web applications. Youíll also study a detailed methodology for performing a comprehensive and deep attack against a specific target. By the end of this book, youíll be able to discover security flaws in web applications and how to deal with them.

Figure 21.11 Testing for shared hosting vulnerabilities

10.1 Test Segregation in Shared Infrastructures

  1. 10.1.1 If the application is hosted in a shared infrastructure, examine the access mechanisms provided for customers of the shared environment to update and manage their content and functionality. Consider the following questions:
    • Does the remote access facility use a secure protocol and suitably hardened infrastructure?
    • Can customers access files, data, and other resources that they do not legitimately need to access?
    • Can customers gain an interactive shell within the hosting environment and execute arbitrary commands?
  2. 10.1.2 If a proprietary application is used to allow customers to configure and customize a shared environment, consider targeting this application as a way to compromise the environment itself and individual applications running within it.
  3. 10.1.3 If you can achieve command execution, SQL injection, or arbitrary file...
