What is XSS (Cross-Site Scripting)

Introduction

Cross-Site Scripting (XSS) is one of the most prevalent vulnerabilities on the internet. It is a web vulnerability that permits malicious actors to inject and execute unauthorized scripts in web pages viewed by unsuspecting users. These scripts typically originate from untrusted sources, such as user input fields or URLs.

When users interact with a compromised page, the injected scripts can execute within their browsers. One notable variant of XSS attacks is Reflected XSS. In reflected XSS attacks, the attacker deceives users into clicking on manipulated links that contain malicious scripts. The vulnerable website subsequently reflects the injected code back to the user's browser, executing it within the context of the website.

The consequences of XSS attacks can be severe for both individuals and organizations. Potential repercussions include data theft, account hijacking, and the distribution of malicious content. To mitigate these threats, it is critical to stay vigilant, keep systems updated, and promote a security-first mindset while navigating the digital landscape.
