Kubernetes 1.3.x < 1.7.14 / 1.8.x < 1.8.9 / 1.9.x < 1.9.4 multiple vulnerabilities

critical Nessus Plugin ID 124590

Synopsis

The remote host contains an application affected by multiple vulnerabilities.

Description

The version of Kubernetes installed on the remote host is version 1.3.x prior to 1.7.14, 1.8.x prior to 1.8.9 or 1.9.x prior to 1.9.4. It is, therefore, affected by multiple vulnerabilities.

- An arbitrary file access vulnerability exists in containers using subpath volume mounts. An authenticated, local attacker can exploit this to access arbitrary files or directories including the host's filesystem.
(CVE-2017-1002101)

- An arbitrary file deletion vulnerability exists in containers using a secret, configMap, projected or downwardAPI volume. An unauthenticated, local attacker can exploit this to delete arbitrary files or directories from the nodes where they are running. (CVE-2017-1002102)

Solution

Upgrade to Kubernetes 1.7.14, 1.8.9, 1.9.4 or later, please refer to the vendor advisory.
