Rooted. Fun box.
I’ve done many boxes harder than this one, but if it has taught me anything it was to just write down what I’ve found and chill. Think with what you have.
This post has everything anyone needs to root the box.
Foothold: What do you have? What your enumeration has told you? You can only go so far, so think what’s the most important thing you need to continue. Before you bring in the big guns, try simple things. Sometimes the answer is just as simple.
User: Really a straightforward path from the foothold. You can do this, and then go there, etc. You’ll get it.
Root: I only found a few relevant things to privesc, but one of them was screaming at my face, so I google it and got root under 10 minutes. There are some excellent writings, let me tell you.
