XSS-Scanner

Are you sure that your application is safe?
Cross-site scripting (XSS) is the most prevalent web application security flaw.

XSS scanner walks through all reachable pages of your web-site and checks all forms that can be potentially vulnerable.

XSS-Scanner is a multi-threading app that works in parallel in several browser windows to save time and improve efficiency.

After working, it creates a nice web page with a report of a test result.

This app is absolutely free XSS Scanner, based on Selenium Web Driver. It scans directly in your browser. All you need is FireFox with FireFoxDriver (usually it is built-in).

Here you can find a self-sufficient source, feel free to use and extend it if needed:

To check vulnerabilities, XSS-scanner uses a list of known XSS-injection provided by owasp:

Let's test and keep safe!
