Vulnerability from github – Published: 2022-08-31 22:29 – Updated: 2022-09-08 14:26

Summary

NVFLARE unsafe deserialization due to Pickle

Details

Impact

NVFLARE contains a vulnerability where deserialization of Untrusted Data due to Pickle usage may allow an unprivileged network attacker to cause Remote Code Execution, Denial Of Service, and Impact to both Confidentiality and Integrity.

All versions before 2.1.4 are affected.

CVSS Score = 9.8

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Patches

The patch is included in nvflare==2.1.4 This new version uses MessagePack instead of Pickle to do serialization and deserialization.

Some object serializations supported by Pickle are not supported by MessagePack. We have provided out of box support for some built-in NVFLARE objects. For object serializations unsupported by MessagePack, the user will need to convert the objects to numpy or bytes before sending over to remote machines. The list of supported object types are listed in https://github.com/NVIDIA/NVFlare/blob/2.1/nvflare/fuel/utils/fobs/README.rst

Workarounds

No workarounds available.
