Kubernetes' First Major Security Hole Discovered (zdnet.com)

Kubernetes has become the most popular cloud container orchestration system by far, so it was only a matter of time until its first major security hole was discovered. And the bug, CVE-2018-1002105, aka the Kubernetes privilege escalation flaw, is a doozy. It's a CVSS 9.8 critical security hole. From a report: With a specially crafted network request, any user can establish a connection through the Kubernetes application programming interface (API) server to a backend server. Once established, an attacker can send arbitrary requests over the network connection directly to that backend. Adding insult to injury, these requests are authenticated with the Kubernetes API server's Transport Layer Security (TLS) credentials. Can you say root? I knew you could. Worse still, "In default configurations, all users (authenticated and unauthenticated) are allowed to perform discovery API calls that allow this escalation." So, yes, anyone who knows about this hole can take command of your Kubernetes cluster.

    My understanding is this is only exploitable by people who have access to Kubernetes anyway. Your firewall should not be routing any traffic from the general internet to the Kubernetes api. So this is a good opportunity to check to make sure your firewall is configured correctly, but if you are vulnerable to outside threats, the problems run deeper than a single vuln you'll want to look seriously at your processes and make sure they are security focused. (Or make them more security focused than they are now).

      If money and space didn't matter it would usually be best to run each service on it's own physical server.
      Since money matters we know we can't do that, as a matter of fact when money mattered the most it was common for a single production server to be running all sorts of unrelated services.
      Virtualization was a sort of happy medium.
      Competition among virtualization solutions brought about a whole slew of really useful features
      Kubernetes provides all of these benefits plus it's lighter weight plus it can be used to roll out to virtual machines, containers, or a single container on a single server as a sort of quasi bare metal.
      And just cause it's cool and maybe it will be useful. You can write a program out of FaaS lambdas, "load" the program onto your distributed computing network, and run it. Sure it's got some crazy overhead and latency compared to running it on your computer. I have 20 reasonably fast cores and an oc'd 4 core i5 which has one of the highest single thread ratings on the market stock. Then if I ever get around to reassembling it I have cluster of a few x86 and a bunch of arm sbcs too probably totaling around 40 cores.
      I have no idea what I can do with all that but it way exceeds my home networking needs my wife does some AI work so maybe eventually I'll show her how to use it.

      Where do you draw the line between “VMs” and “containers”? Docker, for example, is considered a container (or, rather, a deployment mechanism for containers). But Docker uses Hyper-V as its isolation mechanism. So you are really using VMs.

      If they are virtual, you can put them anywhere. So 12 “VMs” running on any number of hypervisors is pretty much identical to running 12 “containers” on any combination of machines, virtual or otherwise.

      That is not the point. There is a loose coupling between the VM and the application. Which means you are never 100% sure your application runs in the environment it was intended for. With containerisation the application always runs in the environment it was intended for regardless of the infrastructure/vm's. Kubernetes is about devops, not about infrastructure.

      if you think docker is a vm, you should read about it more and stay away from the technology until you do.

      VMs use their own guest operating system, containers use the host operating system- a very important difference.

      From TFA:

      A pod exec/attach/portforward API call can be escalated to perform any API request against the kubelet API on the node specified in the pod spec (e.g. listing all pods on the node, running arbitrary commands inside those pods, and obtaining the command output). Pod exec/attach/portforward permissions are included in the admin/edit RBAC roles intended for namespace-constrained users.
