Kubernetes 1.11.x < 1.11.9 / 1.12.x < 1.12.7 / 1.13.x < 1.13.5 kubectl directory traversal

medium Nessus Plugin ID 128650

Language:

Synopsis

The remote host contains an application affected by a directory traversal vulnerability.

Description

The version of Kubernetes installed on the remote host is version 1.11.x prior to 1.11.9, 1.12.x prior to 1.12.7 or 1.13.x prior to 1.13.5. It is, therefore, affected by a directory traversal vulnerability in the kubectl cp command due to mishandling of symlinks when copying files from a running container. An unauthenticated, remote attacker can exploit this, by convincing a user to use kubectl cp with a malicious container to overwrite arbitrary files on the remote host.

Solution

Upgrade to Kubernetes 1.11.9, 1.12.7, 1.13.5, 1.14.0 or later, please refer to the vendor advisory.
