AI-Generated

A vulnerability in Submariner allows a malicious cluster to redirect network traffic from connected peer clusters by publishing a crafted network endpoint, exploiting improper validation of network subnets. This could lead to unauthorized information disclosure or network disruption as traffic is rerouted through the attacker's tunnel. Organizations utilizing Submariner in their cluster environments should prioritize patching this critical issue to safeguard their network integrity.

Original NVD Description

A flaw was found in Submariner. This vulnerability allows a malicious cluster (spoke) to redirect network traffic from other connected clusters (peer clusters) by publishing a specially crafted network endpoint. The system fails to properly validate the network subnets provided by the malicious cluster, enabling it to declare arbitrary network ranges. Consequently, all network traffic intended for these arbitrary ranges from peer clusters will be rerouted through the attacker's tunnel, potentially leading to unauthorized information disclosure or network disruption.
