/**
 * This is a basic phantomJS script that will be used together
 * with the xssValidator burp extender.
 *
 * This script launches a web server that listens by default 
 * on 127.0.0.1:8093. The server listens for POST requests with 
 * http-response data.
 *
 * http-response should contain base64 encoded HTTP response as
 * passed from burp intruder. The server will decode this data, 
 * and build a WebPage bassed of the markup provided.
 *
 * The WebPage will be injected with the js-overrides.js file, 
 * which contains triggers for suspicious JS functions, such as
 * alert, confirm, etc. The page will be evaluated, and the DOM
 * triggers will alert us of any suspicious JS.

xssValidator是burpsuite下商店就可以找到，至于phantomjs（PhantomJS是一个无界面的,可脚本编程的WebKit浏览器引擎。它原生支持多种web 标准：DOM 操作，CSS选择器，JSON，Canvas 以及SVG。）自己百度下。

先执行phantomjs.exe xss.js

然后如下操作：

将可能存在XSS的标记然后发送到Intruder如下操作

切换到xssValidator如下图

标红的地方就是等下成功payload会打勾的地方，相当于这个def就是一个成功的标识。

将标识添加进去

然后开始攻击。

如下图所示成功的payload会被打勾

如果要复制直接根据下面的操作直接复制就可以
