Rancher < 1.6.25 / 2.0.9 / 2.1.3 Kubernetes Proxy Request Handling

critical Nessus Plugin ID 119779

Language:

Synopsis

A Docker container of Rancher installed on the remote host is missing a security patch.

Description

The version of a Docker container of Rancher is prior to 1.6.25, 2.0.9, or 2.1.3 and, thus, is affected by a proxy request handling flaw contained in Kubernetes.

A remote, unauthenticated attacker may be able to leverage API calls to escalate privileges via proxy request handling vulnerability.

Note that a successful attack requires that an API extension server is directly accessible from the Kubernetes API server's network or that a cluster has granted pod exec, attach, port-forward permissions too loosely.

Solution

Upgrade to version 1.6.25, 2.0.9, 2.1.3 or later.
