Vulnerabilities

vantage6 is an open source framework built to enable, manage and deploy privacy enhancing technologies like Federated Learning and Multi-Party Computation. If attacker gets access to an authenticated session, they can try to brute-force the user password by using the change password functionality: they can call that route infinitely which will return the message that password is wrong until it is correct. This vulnerability is fixed in 4.11.

vantage6 is an open source framework built to enable, manage and deploy privacy enhancing technologies like Federated Learning and Multi-Party Computation. The vantage6 server has no restrictions on CORS settings. It should be possible for people to set the allowed origins of the server. The impact is limited because v6 does not use session cookies. This issue has been addressed in commit `70bb4e1d8` and is expected to ship in subsequent releases. Users are advised to upgrade as soon as a new release is available. There are no known workarounds for this vulnerability.

vantage6-UI is the official user interface for the vantage6 server. In affected versions a number of security headers are not set. This issue has been addressed in commit `68dfa6614` which is expected to be included in future releases. Users are advised to upgrade when a new release is made. While an upgrade path is not available users may modify the docker image build to insert the headers into nginx.

vantage6-UI is the User Interface for vantage6. The docker image used to run the UI leaks the nginx version. To mitigate the vulnerability, users can run the UI as an angular application. This vulnerability was patched in 4.2.0.

The vantage6 technology enables to manage and deploy privacy enhancing technologies like Federated Learning (FL) and Multi-Party Computation (MPC). 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. The vulnerability can be mitigated by removing the ssh part from the docker file and rebuilding the docker image. Version 4.2.0 patches the vulnerability.

vantage6 is a framework to manage and deploy privacy enhancing technologies like Federated Learning (FL) and Multi-Party Computation (MPC). In affected versions 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. This impacts all servers that are breached by an expert user. This vulnerability has been patched in version 4.1.2. All users are advised to upgrade. There are no known workarounds for this vulnerability.

vantage6 is privacy preserving federated learning infrastructure. Versions prior to 4.0.0 use pickle, which has known security issue, as a default serialization module but that has known security issues. All users of vantage6 that post tasks with the default serialization are affected. Version 4.0.0 contains a patch. Users may specify JSON serialization as a workaround.

vantage6 is a privacy preserving federated learning infrastructure for secure insight exchange. Currently, the refresh token is valid indefinitely. The refresh token should get a validity of 24-48 hours. A fix was released in version 3.8.0.

vantage6 is a privacy preserving federated learning infrastructure for secure insight exchange. vantage6 does not inform the user of wrong username/password combination if the username actually exists. This is an attempt to prevent bots from obtaining usernames. However, if a wrong password is entered a number of times, the user account is blocked temporarily. This issue has been fixed in version 3.8.0.
