Kubernetes 1.x < 1.10.11 / 1.11.x < 1.11.5 / 1.12.x < 1.12.3 API Server Privilege Escalation

critical Nessus Plugin ID 119327

Language:

Synopsis

The remote host contains an application affected by a privilege escalation vulnerability.

Description

The version of Kubernetes installed on the remote host is version 1.x prior to 1.10.11, 1.11.x prior to 1.11.5, or 1.12.x prior to 1.12.3, and thus, is affected by a remote, unauthenticated privilege escalation 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, portforward permissions too loosely.

Solution

Upgrade to Kubernetes 1.10.11, 1.11.5, 1.12.3 or later.
