CyberRota Analysis
AI-GeneratedA critical vulnerability exists in the submariner-operator component, where the `submariner-k8s-broker-cluster` Role has excessive permissions that can be exploited by an attacker on a compromised cluster. This flaw allows the attacker to modify network configurations and redirect inter-cluster tunnel traffic, facilitating a Man-in-the-Middle (MITM) attack across the cluster mesh. Organizations utilizing submariner for Kubernetes networking should prioritize immediate remediation to mitigate the risk of unauthorized access and data interception.
Original NVD Description
A flaw was found in the submariner-operator component. The `submariner-k8s-broker-cluster` Role, which is assigned to joined clusters, possesses excessive permissions. This allows a compromised cluster to alter network configurations, specifically by overwriting other clusters' endpoint information. Consequently, an attacker can redirect inter-cluster tunnel traffic, enabling a Man-in-the-Middle (MITM) attack across the entire cluster mesh.
