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

High severity GitHub Reviewed Published Nov 14, 2023 in vantage6/vantage6 • Updated Nov 22, 2024

Package

pip vantage6-node (pip)

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

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
