CVE-2024-11393 is a remote code execution vulnerability affecting Hugging Face Transformers in the MaskFormer model file parsing path. The flaw is caused by insufficient validation of user-supplied model data, leading to deserialization of untrusted data. If a target user visits a malicious page or opens a malicious file that triggers processing of a crafted model file, an attacker can execute arbitrary code in the security context of the current user. The issue is identified as ZDI-CAN-25191.

This repository demonstrates a proof-of-concept exploit for CVE-2024-11393, a remote code execution vulnerability in the Hugging Face Transformers library's MaskFormer model conversion script. The vulnerability arises from unsafe deserialization of untrusted pickle files in the 'convert_maskformer_swin_to_pytorch.py' script. The repository contains three files: a LICENSE, a README.md with detailed vulnerability analysis and exploitation instructions, and 'exploit.py', which generates a malicious pickle file ('malicious.pkl'). When this file is loaded by the vulnerable script, it executes a reverse shell command, connecting the victim's machine to an attacker-controlled server. The exploit requires the attacker to supply a crafted pickle file and the victim to run the vulnerable script with this file as input. The main attack vector is local, as the exploit is triggered by the victim running a script with attacker-supplied input. The repository is operational, providing a working payload and clear exploitation steps.
