Invesalius 3.1 Arbitrary File Write / Directory Traversal

Proof of concept python3 code that creates a malicious payload to exploit an arbitrary file write via directory traversal in Invesalius version 3.1. In particular the exploitation steps of this vulnerability involve the use of a specifically crafted .inv3 (a custom extension for InVesalius) that is indeed a tar file file which, once imported inside the victim's client application allows an attacker to write files and folders on the disk.
