Affected Products

  o Vulnerable Products

    This vulnerability affects Cisco HyperFlex Software releases prior to 3.5
    (2g).

    Determining the HyperFlex Software Release

    To determine the installed release of Cisco HyperFlex Software, an
    administrator may use either the CLI or the GUI.

    Using the CLI, the administrator can issue the stcli about command. The
    following example shows the output of the command for a device that is
    running Cisco HyperFlex Software Release 3.0(1d):

        root@hxcluster:~# stcli about
        serviceType: stMgr
        instanceUuid: c4f0441c-xxxx-xxxx-xxxx-xxxxxxxxxxxx
        name: HyperFlex StorageController
        locale: English (United States)
        serialNumber: WZP#####OCD,WZP#####OG9,WZP########
        apiVersion: 0.1
        modelNumber: HX240C-M5L
        build: 3.0.1d-29754 (internal)
        displayVersion: 3.0(1d)
        fullName:  HyperFlex StorageController 3.0.1d
        productVersion: 3.0.1d-29754

    Using the GUI, the administrator can click the About link at the bottom
    left of the page after logging in to HX Connect.

    Products Confirmed Not Vulnerable

    Only products listed in the Vulnerable Products section of this advisory
    are known to be affected by this vulnerability.

Workarounds

  o A workaround for this vulnerability is available for customers who cannot
    upgrade to a fixed release. To coordinate implementation of the workaround,
    contact the Cisco Technical Assistance Center (TAC) .

Fixed Software

  o Cisco has released free software updates that address the vulnerability
    described in this advisory. Customers may only install and expect support
    for software versions and feature sets for which they have purchased a
    license. By installing, downloading, accessing, or otherwise using such
    software upgrades, customers agree to follow the terms of the Cisco
    software license:
    https://www.cisco.com/c/en/us/products/end-user-license-agreement.html

    Additionally, customers may only download software for which they have a
    valid license, procured from Cisco directly, or through a Cisco authorized
    reseller or partner. In most cases this will be a maintenance upgrade to
    software that was previously purchased. Free security software updates do
    not entitle customers to a new software license, additional software
    feature sets, or major revision upgrades.

    When considering software upgrades, customers are advised to regularly
    consult the advisories for Cisco products, which are available from the
    Cisco Security Advisories and Alerts page , to determine exposure and a
    complete upgrade solution.

    In all cases, customers should ensure that the devices to be upgraded
    contain sufficient memory and confirm that current hardware and software
    configurations will continue to be supported properly by the new release.
    If the information is not clear, customers are advised to contact the Cisco
    Technical Assistance Center (TAC) or their contracted maintenance
    providers.

    Customers Without Service Contracts

    Customers who purchase directly from Cisco but do not hold a Cisco service
    contract and customers who make purchases through third-party vendors but
    are unsuccessful in obtaining fixed software through their point of sale
    should obtain upgrades by contacting the Cisco TAC:
    https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html

    Customers should have the product serial number available and be prepared
    to provide the URL of this advisory as evidence of entitlement to a free
    upgrade.

    Fixed Releases

    Cisco fixed this vulnerability in Cisco HyperFlex 3.5(2g).

    Customers can download software updates from the Software Center on
    Cisco.com by doing the following:

     1. Click Browse all .
     2. Navigate to Hyperconverged Infrastructure > HyperFlex HX Data Platform 
        .
     3. Access releases by using the left pane of the HyperFlex HX Data
        Platform page.
