Compressor

OVERVIEW

---

So we were given an instance so let’s start it and head to our attacker machine to nc into it

Here we can see there is a choosing components functionality in which there is a function to create artifact in the form of zip

Seeing this I think about zip vulnerabilities but then i thought let’s start from GTFO bins

Bravo! We got a way to spawn an interactive shell so let’s use it

Let’s Start with creating an Artifact first by choosing option 1

Artifact is created successfully now choose 3 to compress artifact into zip and enter payload inside it as shown below

Here we go We got the shell and also the directory in which we are so just now go to ctf directory and get the flag.txt

WE FINALLY DID IT !!!! CHALLENGE SOLVED !!
