- Summary
- Jupyter Enterprise Gateway Has Kubernetes Manifest Injection via Jinja2 Template Rendering
- Details
-
Jupyter Enterprise Gateway launches remote Jupyter Notebook kernels across distributed clusters like Apache Spark, Kubernetes, and Docker Swarm. In versions prior to 3.3.0, the server interpolates untrusted environment variables (e.g., KERNELXXX) into Kubernetes manifests without YAML-aware escaping, enabling YAML injection attacks. Attackers can inject new fields, overwrite critical fields (e.g., duplicate securityContext keys, where the last one prevails), and inject document boundaries (--- for new documents, ... for end-of-document) to generate multiple resources, potentially creating arbitrary types, such as privileged pods. The Jinja2 template for the Kubernetes manifest contains several kernelxxx variables, such as kernelworkingdir that are used when rendering the manifest and are all vectors for YAML injection. This issue has been fixed in version 3.3.0.
