TorchServe ZipSlip

Moderate severity GitHub Reviewed Published Nov 21, 2023 in pytorch/serve • Updated Nov 21, 2023

Package

pip torchserve (pip)

Affected versions

>= 0.1.0, < 0.9.0

Patched versions

0.9.0

Description

Impact

Using the model/workflow management API, there is a chance of uploading potentially harmful archives that contain files that are extracted to any location on the filesystem that is within the process permissions. Leveraging this issue could aid third-party actors in hiding harmful code in open-source/public models, which can be downloaded from the internet, and take advantage of machines running Torchserve.

Patches

The ZipSlip issue in TorchServe has been fixed by validating the paths of files contained within a zip archive before extracting them: pytorch/serve#2634

TorchServe release 0.9.0 includes fixes to address the ZipSlip vulnerability:
https://github.com/pytorch/serve/releases/tag/v0.9.0

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
