vantage6 has insecure SSH configuration for node and server containers

Moderate severity GitHub Reviewed Published Jan 30, 2024 in vantage6/vantage6 • Updated Feb 8, 2024

Package

pip vantage6 (pip)

Affected versions

< 4.2.0

Patched versions

4.2.0

Description

Impact

Nodes and servers get a ssh config by default that permits root login with password authentication. In a proper deployment, the SSH service is not exposed so there is no risk, but not all deployments are ideal. The default should therefore be less permissive.

We will probably opt to completely remove the ssh option as it is only used for debugging. Later, we can add a debug mode where we can activate it if necessary.

Workarounds

Remove the ssh part from the docker file and build your own docker image

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.
