vantage6-server node accepts non-whitelisted algorithms from malicious server
Date: 2023-11
Affected: pip/vantage6-node, pip/vantage6-server
Attack vector: other
Category: vulnerability-disclosure
Severity: High
CVE: CVE-2023-47631
CWE: CWE-345
CWE-358
CVSS: 7.2 (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H)

### 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
