Background
TorchServe is an open-source model serving library for PyTorch models. It provides an API for managing models and workflows. TorchServe allows users to upload and serve models, but it was found to be vulnerable to a ZipSlip issue. This vulnerability could allow malicious actors to upload harmful archives containing files that are extracted to any location on the filesystem within the process permissions. This could enable the hiding of harmful code in open-source/public models, which can be downloaded and executed on machines running TorchServe.
Vulnerability Detail
The ZipSlip vulnerability in TorchServe allows for the extraction of files from potentially harmful archives to arbitrary locations on the filesystem. This can be exploited by uploading malicious archives that contain files with malicious code. The extracted files can then be executed within the process permissions, potentially leading to unauthorized access, data leakage, or remote code execution. This vulnerability poses a moderate risk to systems running TorchServe.
