vantage6-server node accepts non-whitelisted algorithms from malicious server

High severity GitHub Reviewed Published Nov 14, 2023 in vantage6/vantage6 • Updated Nov 14, 2023

Package

pip vantage6-server (pip)

Affected versions

< 4.1.2

Patched versions

4.1.2

Description

Impact

A node does not check if an image is allowed to run if a parent_id is set. A malicious party that breaches the server may modify it to set a fake parent_id and send a task of a non-whitelisted algorithm. The node will then execute it because the parent_id that is set prevents checks from being run. Relevant node code here

This impacts all servers that are breached by an expert user
