Anti-XSS Library v3.1 Released!

The Microsoft Information Security Tools (IST) team has released the latest Microsoft Anti-Cross Site Scripting (Anti-XSS) Library version 3.1. How does a cross-site scripting (XSS) vulnerability occur? An example is when a web application does not encode the output that is sent to the browser, this can make the site susceptible XSS attacks as well as other common attacks. Using XSS attacks, malicious users can cause damage to a site including hijacking a client session, stealing a web session information as well as cookies and more. The Anti-XSS Library v3.1 is an encoding library specifically designed to help developers protect their ASP.NET web-based applications from XSS attacks. Watch the video, “Anti-XSS 3.0 Released,” as Vineet Batta and Anil Revuru (RV), Senior Software Developers from the Microsoft Information Security Tools (IST), provide an overview of the Anti-XSS Library and how it can prevent XSS attacks in your application. The key new feature in Anti-XSS v3.1 is sanitization of HTML pages and fragments, ensuring all malicious scripts are removed and enabling the input safe to display to the browser.
