Scenario: Exploitation of a Cross-Site Scripting Vulnerability

Imagine a popular online shopping website with a vulnerability allowing attackers to inject malicious JavaScript code into user profiles. This vulnerability, known as Cross-Site Scripting (XSS), could allow attackers to steal user credentials, redirect users to malicious websites, or even take control of their accounts.

Scenario:A user visits the online shopping website and logs into their account. An attacker exploits the XSS vulnerability by injecting malicious JavaScript code into the user’s profile page. When the user visits their profile, the malicious code executes, stealing their login credentials and redirecting them to a fake website designed to look like the real one.

The attacker now has access to the user’s account and can use it to make unauthorized purchases or steal sensitive information.

Sometimes, the best way to expose the vulnerabilities of a system is to look at its history.
