CSRF - Lab #2 CSRF where token validation depends on request method | Long Version

In this video, we cover Lab #2 in the CSRF module of the Web Security Academy. This lab's email change functionality is vulnerable to CSRF. It attempts to block CSRF attacks, but only applies defenses to certain types of requests. To solve the lab, we craft some HTML that uses a CSRF attack to change the viewer's email address and upload it to to our exploit server. ▬ 🌟 Video Sponsor 🌟 ▬▬▬▬▬▬▬▬▬▬ Sign up to Intigriti: https://go.intigriti.com/ranakhalil (affiliate link) ▬ ✨ Support Me ✨ ▬▬▬▬▬▬▬▬▬▬ Buy my course: https://academy.ranakhalil.com/p/web-security-academy-video-series ▬ 📖 Contents of this video 📖 ▬▬▬▬▬▬▬▬▬▬ 00:00 - Introduction 00:15 - Intigriti sponsorship (https://go.intigriti.com/ranakhalil) 01:09 - Navigation to the exercise 01:49 - Understand the exercise and make notes about what is required to solve it 02:39 - Exploit the lab using Burp Suite Pro 12:42 - Script the exploit (without Burp Suite Pro) 21:07 - Summary 21:27 - Thank You ▬ 🔗 Links 🔗 ▬▬▬▬▬▬▬▬▬▬ HTML script: https://github.com/rkhal101/Web-Security-Academy-Series/blob/main/csrf/lab-02/csrf-lab-02.html Notes.txt document:https://github.com/rkhal101/Web-Security-Academy-Series/blob/main/csrf/lab-02/notes.txt CSRF Lab #1 (previous video): https://www.youtube.com/watch?v=BBosVSNiJdM&ab_channel=RanaKhalil CSRF theory video: https://www.youtube.com/watch?v=7bTNMSqCMI0&ab_channel=RanaKhalil Web Security Academy Youtube Video Series Release Schedule: https://docs.google.com/spreadsheets/d/16ypyLuDq2DZ1JAz_WvL1ZV-WiDWhvomgrK_1Hux4MFY/edit#gid=0 Web Security Academy: https://portswigger.net/web-security/csrf/lab-token-validation-depends-on-request-method Rana's Twitter account: https://twitter.com/rana__khalil
