SockJS Exploit | Rahad Chowdhury 

What is SockJS?
SockJS is a JavaScript library (for browsers) that provides a WebSocket-like object. SockJS gives you a coherent, cross-browser, Javascript API which creates a low latency, full duplex, cross-domain communication channel between the browser and the web server, with WebSockets or without. This necessitates the use of a server, which this is one version of, for Node.js.

There is a Reflected XSS Vulnerability in SockJS on versions before of 3.0.
