CyberRota Analysis

AI-Generated

Kubernetes versions prior to 1.0.2 and 1.1.2 are vulnerable due to a lack of authentication for management APIs exposed on the external agent listener, enabling attackers to execute commands in workload pods and access the data-plane Kubernetes API. This critical vulnerability poses a significant risk to multi-cluster deployments, as it allows unauthorized network access to sensitive operations. Organizations using affected versions should prioritize immediate upgrades to the patched versions to mitigate potential exploitation.

Original NVD Description

OpenChoreo is a complete, open-source developer platform for Kubernetes. Prior to 1.0.2 and 1.1.2, internal/cluster-gateway/server.go served caller-facing management APIs on the externally reachable agent listener without authentication, allowing network-reachable attackers to invoke /api/proxy/ and /api/exec/ operations, proxy the data-plane Kubernetes API, and execute commands in workload pods in multi-cluster deployments. This issue is fixed in versions 1.0.2 and 1.1.2.
