What Exactly Happens after a Link Failure?

Imagine the following network running OSPF as the routing protocol. PE1–P1–PE2 is the primary path and PE1–P2–PE2 is the backup path. What happens on PE1 when the PE1–P1 link fails? What happens on PE2?

New Vulnerability Exposes Kubernetes to Man-in-the-Middle Attacks: Here’s How to Mitigate

What is CVE-2020-8554?

A few weeks ago a solution engineer discovered a critical flaw in Kubernetes architecture and design, and announced that a “security issue was discovered with Kubernetes affecting multi-tenant clusters. If a potential attacker can already create or edit services and pods, then they may be able to intercept traffic from other pods (or nodes) in the cluster.” If a hostile user can create a ClusterIP service and set the spec.externalIP field, they can intercept traffic to that IP. In addition, if a user can patch the status of a LoadBalancer service, which is a privileged operation, they can also intercept traffic by exploiting the vulnerability.

Who is Affected?

All Kubernetes versions including the latest release v1.20 are vulnerable to this attack, with the most significant impact being to multi-tenant clusters. Multi-tenant clusters that grant tenants the ability to create and update services and pods are most vulnerable. Since this is a major design flaw with no fix in sight, it becomes imperative to understand and mitigate this CVE.

Technical Overview

The man-in-the-middle (MITM) attack starts with step 1 (shown in the diagram, below). A workload sends a connection request to legitimate IP 4.4. Continue reading
