Summary

    A vulnerability in the web-based UI of Cisco HyperFlex HX Data Platform
    Software could allow an unauthenticated, remote attacker to access
    sensitive information on an affected system.

    The vulnerability is due to a lack of proper input and authorization of
    HTTP requests. An attacker could exploit this vulnerability by sending a
    malicious HTTP request to the web-based UI of an affected system. A
    successful exploit could allow the attacker to access files that may
    contain sensitive data.

    There are no workarounds that address this vulnerability.

Cisco Security Advisory

Cisco HyperFlex Software Static Signing Key Vulnerability

Priority:           High
Advisory ID:        cisco-sa-20181003-hyperflex-secret
First Published:    2018 October 3 16:00 GMT
Version 1.0:        Final
Workarounds:        No workarounds available
Cisco Bug IDs:      CSCvj95632, CSCvk22858
CVE-2018-15382
CWE-642 
CVSS Score:         Base 8.6
CVSS:               3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H/E:X/RL:X/RC:X

Summary

    A vulnerability in Cisco HyperFlex Software could allow an unauthenticated,
    remote attacker to generate valid, signed session tokens.

    The vulnerability is due to a static signing key that is present in all
    Cisco HyperFlex systems. An attacker could exploit this vulnerability by
    accessing the static signing key from one HyperFlex system and using it to
    generate valid, signed session tokens for another HyperFlex system. A
    successful exploit could allow the attacker to access the HyperFlex Web UI
    of a system for which they are not authorized.

    Cisco has released software updates that address this vulnerability. There
    are no workarounds that address this vulnerability.

    This advisory is available at the following link:
    https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-hyperflex-secret

Affected Products

  o Vulnerable Products

    This vulnerability affects Cisco HyperFlex Software releases prior to 3.5
    (1a).

    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 on the bottom
    left of the page after logging in to HXConnect.

    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 There are no workarounds that address this vulnerability.

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(1a).

    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.

Exploitation and Public Announcements

  o The Cisco Product Security Incident Response Team (PSIRT) is not aware of
    any public announcements or malicious use of the vulnerability that is
    described in this advisory.

Source

  o This vulnerability was found during internal security testing.

CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:N/I:L/A:L/E:X/RL:X/RC:X

Summary

    A vulnerability in the web UI of Cisco HyperFlex Software could allow an
    unauthenticated, remote attacker to affect the integrity of a device via a
    clickjacking attack.

    The vulnerability is due to insufficient input validation of iFrame data in
    HTTP requests that are sent to an affected device. An attacker could
    exploit this vulnerability by sending crafted HTTP packets with malicious
    iFrame data. A successful exploit could allow the attacker to perform a
    clickjacking attack where the user is tricked into clicking a malicious
    link.

    There are no workarounds that address this vulnerability.
