Red Hat OpenShift Enterprise 3.2 and 3.1 do not properly validate the origin of a request when anonymous access is granted to a service/proxy or pod/proxy API for a specific pod, which allows remote attackers to access API credentials in the web browser localStorage via an access_token in the query parameter.

The remote Red Hat Enterprise Linux CoreOS 3 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2016:1095 advisory.

  - 3: Untrusted content loaded via the API proxy can access web console credentials on the same domain     (CVE-2016-3703)

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

The remote Red Hat Enterprise Linux CoreOS 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:1094 advisory.

  - 3: Untrusted content loaded via the API proxy can access web console credentials on the same domain     (CVE-2016-3703)

  - 3: s2i builds implicitly perform docker builds (CVE-2016-3708)

  - origin: pod update allows docker socket access via build-pod (CVE-2016-3738)

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

An update for atomic-openshift is now available for Red Hat OpenShift Enterprise 3.1. In addition, all images have been rebuilt on the new RHEL 7.2.4 base image.

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

OpenShift Enterprise by Red Hat is the company's cloud computing Platform-as-a-Service (PaaS) solution designed for on-premise or private cloud deployments.

Security Fix(es) :

* An origin validation vulnerability was found in OpenShift Enterprise. An attacker could potentially access API credentials stored in a web browser's localStorage if anonymous access was granted to a service/proxy or pod/ proxy API for a specific pod, and an authorized access_token was provided in the query parameter.
(CVE-2016-3703)

This issue was discovered by Jordan Liggitt (Red Hat).

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:1094 advisory.

    OpenShift Enterprise by Red Hat is the company's cloud computing Platform-as-a-Service (PaaS) solution     designed for on-premise or private cloud deployments.

    Security Fix(es):

    * A vulnerability was found in the STI build process in OpenShift Enterprise. Access to STI builds was not     properly restricted, allowing an attacker to use STI builds to access the Docker socket and escalate their     privileges. (CVE-2016-3738)

    * An origin validation vulnerability was found in OpenShift Enterprise. An attacker could potentially     access API credentials stored in a web browser's localStorage if anonymous access was granted to a     service/proxy or pod/proxy API for a specific pod, and an authorized access_token was provided in the     query parameter. (CVE-2016-3703)

    * A flaw was found in OpenShift Enterprise when multi-tenant SDN is enabled and a build is run within a     namespace that would normally be isolated from pods in other namespaces. If an s2i build is run in such an     environment the container being built can access network resources on pods that should not be available to     it. (CVE-2016-3708)

    The CVE-2016-3738 issue was discovered by David Eads (Red Hat); the CVE-2016-3703 issue was discovered by     Jordan Liggitt (Red Hat); and the CVE-2016-3708 issue was discovered by Ben Parees (Red Hat).
