The Importance of White-Box Testing: A Dive into CVE-2022-21662
I want to take some time to explain the importance of using a white-box approach when testing applications for vulnerabilities. To help in this endeavor, I will use a real-world example to demonstrate how researchers (in this case Karim El Ouerghemmi and Simon Scannell) *may* have found a vulnerability in WordPress (CVE-2022-21662 a 2nd order stored XSS) and how you, as a security researcher, can also use a white-box approach to find an exotic XSS vulnerability.
