"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2015:2544 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.

    It was found that OpenShift's API back end did not verify requests for
    pod log locations, allowing a pod on a Node to request logs for any
    other pod on that Node. A remote attacker could use this flaw to view
    sensitive information via pod logs that they would normally not have
    access to. (CVE-2015-7528)

    This issue was discovered by Jordan Liggitt of Red Hat Atomic OpenShift.

    All OpenShift Enterprise 3.0 and 3.1 users are advised to upgrade to
    these updated packages, which correct this issue.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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