What to do
AI-suggested
1. Immediate upgrade of Onyxia to version 4.9.0 or later, where the vulnerability is patched, is the most effective mitigation. 2. 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. 3. Review and rotate all credentials for private Helm repositories that were potentially exposed through the vulnerable endpoint to prevent unauthorized access. 4. Implement strict access controls and monitoring on private Helm repositories to detect any unauthorized access or anomalous activity. 5. Employ Kubernetes network policies to limit external access to Onyxia APIs and endpoints. 6. Conduct an audit of all Onyxia deployments to identify instances using private Helm repositories and verify they are updated or mitigated accordingly. 7. 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.
