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 SSRF


The basic idea behind SSRF is to find access to internal resources that can be manipulated to access unauthorized resources. For example, imagine that we have the following URL:

https://site.com/process.php?url=192.168.2.34/data/

In this case, we have a website that is public behind the site.com domain, and it processes something using the information retrieved from an internal IP. If the developer does not validate the url parameter, a malicious user can access unauthorized resources located in the internal IP, or maybe in others that have the same visibility.

To detect this kind of vulnerability, we can use Burp Suite's Scanner, which will detect them automatically, or apply a filter in the Target tool to find requests that have access to other resources.
