Finally root, this took me a lot of effort I’m sure who is familiar with technology involved can solve the box with less trouble than I had.
Foothold/User: analyze carefully what you have and extract useful informations. At some point with enumeration you should be able to find the right path, try not to pollute with too much enumeration.
Root: once you’re in classical enumeration will make you understand that something is behind the scene. Here I had to do a lot of study and google-fu. You need to create something malicious (using same approach as foothold) that could allow you to reach the goal.
I managed to retrieve the flag and a shell, but it was really unstable I don’t know if anybody experienced the same situation.Thanks for the box!
it is not unstable, is HTB that thinks that everything is a “race condition” and cleans everything shortly
