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

Patches

Fixed in v4.1.2

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.
