Cross-namespace Secret disclosure via unchecked references
Published Sep 3, 2024 · Updated Sep 3, 2024
Information disclosure in Metal3 Bare Metal Operator allows remote authenticated users to read cross-namespace Kubernetes Secrets. The getSecretData method uses the namespace supplied by a BareMetalHost userData, metaData, or networkData reference without checking it against the host namespace. Exploitation requires permission to create or edit BareMetalHost resources and exposes only Secret keys named value, userData, metaData, or networkData.
