How to Fix CVE-2024-35198

To remediate this vulnerability, upgrade all affected Torchserve dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

torchserve fixed: 0.11.0 
pip install torchserve>=0.11.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show torchserve

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-35198, inspect your installed packages using pip:

pip show torchserve

Analyze the terminal output to locate any version of Torchserve in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.11.0), your application is affected.

Note: The pip show torchserve command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-706: Use of Incorrectly-Resolved Name or Reference, where the product uses a name or reference to access a resource, but the name/reference resolves to a resource that is outside of the intended control sphere. In Torchserve, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact TorchServe's check on allowed_urls configuration can be by-passed if the URL contains characters such as ".." but it does not prevent the model from being downloaded into the model store. Once a file is downloaded, it can be referenced without providing a URL the second time, which effectively bypasses the allowed_urls security check. Customers using PyTorch inference Deep Learning Containers (DLC) through Amazon SageMaker and EKS are not affected. ### Patches This issue in TorchServe has been fixed by validating the URL without characters such as ".." before downloading: [#3082](https://github.com/pytorch/serve/pull/3082). TorchServe release 0.11.0 includes the fix to address this vulnerability. ### References * [#3082](https://github.com/pytorch/serve/pull/3082) * [TorchServe release v0.11.0](https://github.com/pytorch/serve/releases/tag/v0.11.0) Thank Kroll Cyber Risk for for responsibly disclosing this issue.
