Directory traversal vulnerability in Kubernetes, as used in Red Hat OpenShift Enterprise 3.0, allows attackers to write to arbitrary files via a crafted object type name, which is not properly handled before passing it to etcd.

The remote Red Hat Enterprise Linux CoreOS 3 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2015:1945 advisory.

  - Kubernetes: Missing name validation allows path traversal in etcd (CVE-2015-5305)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the references section.

Kubernetes allows orchestration and control of Docker containers as used in OpenShift Enterprise 3.

Kubernetes fails to validate object name types before passing the data to etcd. As the etcd service generates keys based on the object name type this can lead to a directory path traversal. (CVE-2015-5305)

Red Hat would like to thank Jordan Liggitt for discovering and reporting this issue.
