Vulnerability Details CVEID: CVE-2019-4185 DESCRIPTION: IBM InfoSphere Information Server containers are vulnerable to privilege escalation due to an insecurely configured component. CVSS Base Score: 8.3 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 158975 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:A/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H) Affected Products and Versions The following products, running on all supported platforms, are affected: IBM InfoSphere Information Server: version 11.7.1 IBM InfoSphere Information Server on Cloud: version 11.7.1 Remediation/Fixes None Workarounds and Mitigations Perform the following steps to secure your environment: 1. List your kube-system namespace > kubectl get deployments -n kube-system image-20190425180554-1 2. List the pods in your kube-system namespace > kubectl get deployments -n kube-system image-20190425180646-2 3. Delete the tiller pod > kubectl delete deployment tiller-deploy --namespace=kube-system 4. Verify that the tiller pod was deleted by examining the output of command > kubectl get deployments -n kube-system Verify that helm is working by executing the following command: > helm list The output should contain the list of deployed services. However, if the following error message is displayed: Error: configmaps is forbidden: User "system:serviceaccount:kube-system:default" cannot list resource "configmaps" in API group "" in the namespace "kube-system" Execute the following command: > kubectl patch deploy --namespace kube-system tiller-deploy -p ' {"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}' After 10 to 20 seconds, again check the output of "helm list" as indicated above. NOTE: After making the above changes, if at a later point in time you need to install a patch, you must deploy the tiller pod before installing the patch. Use the following steps: 1. Deploy tiller > /usr/local/bin/helm init 2. Verify that the tiller POD is created by executing the command > kubectl get deployments -n kube-system You should see tiller-deploy listed in the output. 3. Install the patch 4. Repeat the steps listed above to again secure your environment.
