How to Fix CVE-2024-21653

To remediate this vulnerability, upgrade all affected Vantage6 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 fixed: 4.2.0 
pip install vantage6>=4.2.0
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

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-21653, inspect your installed packages using pip:

pip show vantage6

Analyze the terminal output to locate any version of Vantage6 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.2.0), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In Vantage6, 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 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
