CyberRota Analysis

AI-Generated

Kong Mesh's global control plane is vulnerable due to a flaw in the KDS sync mechanism, allowing an authenticated zone to manipulate resources in another zone's namespace by exploiting sender-controlled identifiers. This cross-zone isolation bypass can lead to unauthorized resource injection and overwriting, posing significant risks to multi-zone environments. Organizations utilizing Kong Mesh should prioritize addressing this vulnerability to safeguard their network segmentation and resource integrity.

Original NVD Description

On a Kong Mesh global control plane, resources received over the zone-to-global KDS sync are attributed using the in-band, sender-controlled ControlPlane.Identifier rather than the authenticated zone identity derived from the connection. Authenticated zones can have theĀ global control plane store and re-distribute those resources as belonging to another zone. The result is a cross-zone isolation bypass: the holder of a single enrolled zone's credential can inject, attribute, and overwrite resources in another zone's namespace mesh-wide. The root cause lives in Kuma's open-source KDS sync code, which Kong Mesh's control plane is built on.
