Chapter 10: Identifying Server Vulnerabilities in Web Applications

In this chapter, we will learn about the main vulnerabilities in web applications. We will also learn about the tools we can find in the Python ecosystem to discover vulnerabilities in Content Management System (CMS) web applications and sqlmap for detecting SQL vulnerabilities. In terms of server vulnerabilities, we will cover in detail testing of the Heartbleed vulnerability in servers with OpenSSL activated. We will also cover testing of the SSL/TLS vulnerabilities with the sslyze module.

From a security point of view, it is important to identify server vulnerabilities because applications and services are continually changing, and any unpatched security issue can be exploited by an attacker who aims to exploit vulnerabilities that have not been initially identified. At this point, it is important to note that not all security vulnerabilities can be fixed with a patch, and some even depend on a bug in the application...
