Network Policy Bypass Vulnerability in Kubernetes by The Cloud Native Computing Foundation

CVE-2024-7598

Summary

A vulnerability in Kubernetes has been identified that enables a malicious or compromised pod to bypass network restrictions set by network policies during the deletion of namespaces. This issue arises because the Kubernetes deletion process does not guarantee a defined order of object deletion. As a result, network policies may be removed before the pods they are intended to protect are terminated. This window of vulnerability allows the pods to continue running without the enforcement of the necessary network policies, potentially exposing the system to unauthorized access and exploitation.
