DOM-based attacks are advanced ones made possible when the web application's client-side script writes user-provided data to the DOM. The web application reads the data from the DOM and delivers it to the browser. If the data isn't handled correctly, the attacker is able to inject a payload that will be stored as part of the DOM. The payload is then executed when the data is read back from the DOM.
Advanced Cross-Site-Scripting (XSS)
Cross-Site Scripting(XSS) is a popular and vulnerable attack that is known by every advanced tester. It is considered one of the adventurous attacks on web applications and can bring harmful results also. This attack is considered adventurous, because of its ability to damage even less vulnerable technologies.
The API exposed by Chromium to browser extension is not as powerful and flexible as its Mozilla-developed counterpart.This is already true in Manifest V2, and gets much worse with Manifest V3, especially hurting privacy and security innovation.Therefore, even if NoScript is compatible with most browsers, some of its most advanced features are available only on Firefox and its derivatives, such as the Tor Browser.In details, these are the current limitations imposed to NoScript by Chromium-based browsers such as Google Chrome, Edge or Vivaldi:
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.
