Description

Cross-site scripting (XSS) is a security vulnerability affecting web applications. XSS allows an attacker to execute scripts on the machines of clients of a targeted web application. This can allow attackers to steal credentials and sessions from clients or deliver malware. The Open Web Application Security Project (OWASP) has included XSS in its top ten list of the most critical web application security risks every year the list has been produced. It reports that XSS vulnerabilities are found in two-thirds of all applications.

This Lab demonstrates a reflected cross-site scripting attack. Reflected XSS is sometimes referred to as non-persistent XSS and is the most common kind of XSS. It results from a user clicking a specially-constructed link storing a malicious script that an attacker injects. You will use a web application that is intentionally vulnerable to illustrate the attack.

You will use the web browser on a Kali Linux host to launch the attack on a web application running on a Metasploitable 2 host. Both hosts are running as virtual machines in a Hyper-V virtual environment.

This Lab is designed for the CREST Practitioner Security Analyst (CPSA) certification examination but is of value to security practitioners in general.
