Description

Cross Site Scripting or XSS is still one of the most common injection vulnerability that exist in modern as well as legacy Web Applications. This course will teach XSS in-depth and even talk about the lesser known derivatives of XSS called Mutation XSS (mXSS) and Relative Path Overwrite XSS (RPO XSS). If you are interested in learning about the different types of XSS, different context in XSS, and about real world red team XSS Exploitation, then this course is for you and it does not take hours. Invest just 2 hours and master XSS in-depth.

This course is completely hands-on and every concept is explained with a demo or exercise. This allow students to try out all the things that they have learned. This course explains XSS, its types, context and also discuss about exploiting XSS vulnerabilities in real world where you can perform offensive attacks ranging from Keylogging, Cookie Stealing, Phishing, Victim/Browser/Network Fingerprinting to much advanced attacks like reverse TCP shell, Driveby Attacks etc with OWASP Xenotix XSS Exploit Framework.

OWASP Xenotix XSS Exploit Framework is an Advanced Cross Site Scripting Vulnerability Detection and Exploitation Framework written by the author of this course. Finally we will also discuss about XSS Protection where we discuss about Input Validation, Context Sensitive output escaping and the various security headers that help us to mitigate XSS. Also as a take away you will get "The Ultimate XSS Protection Cheat sheet" from OpenSecurity.

The course will cover the following things.

  • What is XSS?
  • Why XSS?
  • Types of XSS
    • Reflected XSS or Non-Persistent XSS
    • Stored XSS or Persistent XSS
    • DOM XSS
      • mXSS or Mutation XSS
    • RPO or Relative Path Overwrite XSS
  • What are the Source of XSS?
  • Different Contexts in XSS
    • HTML Context
    • Attribute Context
    • URL Context
    • Style Context
    • Script Context
  • Attacks in Real World
  • Exploiting XSS with OWASP Xenotix XSS Exploit Framework
  • XSS Protection
