Overview What You Will Learn Curriculum Instructor

Course Overview

Cross-Site Scripting (XSS) remains one of the most prevalent and dangerous web vulnerabilities, often leading to severe security breaches. Understanding how XSS exploits work in real-world scenarios is crucial for developers, security professionals, and ethical hackers. “Case Studies of Award-Winning XSS Attacks: Part 2” explores advanced XSS techniques successfully leveraged in security research, shedding light on sophisticated exploitation methods that go beyond basic payloads. By studying these case studies, learners gain a deeper understanding of how attackers manipulate web applications and how to build more robust defenses against such threats.

The course begins with an introduction to the importance of XSS research and its impact on web security. It then examines specific exploitation techniques, starting with XSS via XML, where attackers inject malicious scripts into XML-based data structures. Next, it covers XSS via location.href, demonstrating how manipulating JavaScript’s location object can trigger vulnerabilities. Learners then explore XSS via vbscript:, an outdated yet still relevant attack vector in legacy applications. The course culminates with an in-depth case study on “From XSS to Remote Code Execution”, illustrating how XSS can serve as an initial foothold for executing arbitrary commands on a system. Each module includes a hands-on demonstration, ensuring learners can visualize and comprehend the attack techniques in practice.

By the end of this course, participants will be able to identify advanced XSS exploitation techniques, understand their real-world implications, and apply mitigation strategies to secure web applications against these evolving threats.
