Security 防止跨站点脚本攻击？

我们最近建立了一个网站(http://www.doverjewelry.com/)通过hikashop，域具有godaddy网站保护，因此它可以扫描网站并警告漏洞。扫描当前报告网站易受跨站点脚本攻击。这将显示扫描输出：

根据扫描仪的输出，他认为当他发出带有附加参数的请求时：

<<<<<<<<<<foo"bar'314>>>>>=1

看来，附加的param althogh逃走了。。。因此，严格来说，它不容易出现XSS。如果您想了解更多访问信息，可以使用其他vuln扫描仪/代理来确认此问题：ZAP、WebScarab、w3af
 在将来，您应该避免修改库代码，而是重写可以重写的函数。
<<<<<<<<<<foo"bar'314>>>>>=1

type-atom?<<<<<<<<<<foo"bar'314>>>>>=1
