Pretty cool machine. Getting the low priv shell is kinda tricky but thanks to @ghost0437 I was able to get the haha page and call my shell.
User: As you’ve seen in this forum, it’s all about zones. Once you get to this step you’ll have to climb another level to get to the haha page. Make sure you enumerate the brazilian dance to see what can you do (this step will be useful later). Also make sure you enumerate port 443 and you’ll have to edit some files on your end so you can see. Once you’re in the haha page follow the instructions on the screen and call your shell by using the absolute path
Root: g0tm1lk’s guide will point you to the magic file. Once you identify that enumerate what’s running in the system. I used this awesome tool GitHub - DominicBreuker/pspy: Monitor linux processes without root permissions Once you identify the process you should know what’s next to get root.
