What to do
AI-suggested
- Immediate upgrade of Onyxia to version 4.9.0 or later, where the vulnerability is patched, is the most effective mitigation.
- Until the upgrade is applied, restrict access to the /public/catalogs endpoint via network-level controls such as firewalls or API gateways to limit exposure to trusted users only.
- Review and rotate all credentials for private Helm repositories that were potentially exposed through the vulnerable endpoint to prevent unauthorized access.
- Implement strict access controls and monitoring on private Helm repositories to detect any unauthorized access or anomalous activity.
- Employ Kubernetes network policies to limit external access to Onyxia APIs and endpoints.
- Conduct an audit of all Onyxia deployments to identify instances using private Helm repositories and verify they are updated or mitigated accordingly.
- Educate DevOps and security teams about the risks of exposing sensitive credentials in publicly accessible endpoints and enforce secure configuration management practices.
Description
Onyxia is a data science environment for kubernetes. In versions 4.6.0 through 4.8.0, Onyxia-API leaked the credentials of private helm repositories in the public (unauthenticated) /public/catalogs endpoint.vOnly instances using private helm repositories (i.e setting username & password in the catalogs configuration) are affected. This is fixed in version 4.9.0.
