I modified this webshell to only execute my secret parameter.
收集到的信息
用户 h4x0r
webshell /simple-backdoor.php
执行参数 未知
2.3. 获取参数
从收集的这些信息当中猜测Webshell的参数
试了几个参数都不对。猜测可能是需要爆破才行

获取到参数是 secret 之前有在网页试过这个参数。应该是302了导致没有显示出来
抓包的话可以看到
弹shell

3. 提权
这靶机上gcc编译不了。找不到Ld
可以尝试从其他版本相近的靶机编译后传过来。
这里我就不尝试了
使用linpeas进行检测。也没有发现什么利用点
去看一下wp才发现原来这里存在Rootkit
https://github.com/m0nad/Diamorphine
kill -63 0 取消隐藏进程
lsmod 列出加载到内核中的模块
可以看到确实安装了[[…/…/26-工具使用/Diamorphine使用|Diamorphine]]
[[…/…/26-工具使用/Diamorphine使用|海洛因]]有一个特征
我们发送信号64即可获取到root
