medium Nessus Plugin ID 123831

Language:

Synopsis

The remote host contains an application affected by a denial of service vulnerability.

Description

The version of Kubernetes installed on the remote host is version 1.x prior to 1.11.8, 1.12.x prior to 1.12.6 or 1.13.x prior to 1.13.4. It is, therefore, affected by a denial of service vulnerability in the API server. An authenticated, remote attacker can exploit this via a specially crafted patch request of type json-patch to cause the API Server to stop responding.

Solution

Upgrade to Kubernetes 1.11.8, 1.12.6, 1.13.4 or later, refer to the vendor advisory for relevant patch and configuration settings.
