How to Fix CVE-2023-47631

To remediate this vulnerability, upgrade all affected Vantage6 server dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

vantage6-server fixed: 4.1.2 
pip install vantage6-server>=4.1.2
vantage6-node fixed: 4.1.2 
pip install vantage6-node>=4.1.2
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 vantage6-server

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-47631, inspect your installed packages using pip:

pip show vantage6-server

Analyze the terminal output to locate any version of Vantage6 server in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.1.2), your application is affected.

Note: The pip show vantage6-server command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-358: Improperly Implemented Security Check for Standard, where the product does not implement or incorrectly implements one or more security-relevant checks as specified by the design of a standardized algorithm, protocol, or technique. In Vantage6 server, 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 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](https://github.com/vantage6/vantage6/blob/version/4.1.1/vantage6-node/vantage6/node/docker/docker_manager.py#L265-L268) This impacts all servers that are breached by an expert user ### Patches Fixed in v4.1.2 ### Workarounds None
