AppCheck Webinar: Cross-Site Scripting (XSS)

Cross-Site Scripting (XSS) is by far the most widespread high impact vulnerability, present even in the best of web applications, regardless of the framework or programming language employed - a burly steadfast member of the OWASP Top Ten.
Here at AppCheck the client-side nature of typical XSS has led to a general underappreciation of its exploitation potential, though a good understanding of the vulnerability and its subtle variations will show how it can be used to devastating effect... and more importantly: how it can be avoided.
In this seminar we will build up piece-by-piece an understanding of XSS that spares no detail.
