CVE-2018-0270

Summary

  * 
    A vulnerability in the web-based management interface of Cisco IoT Field
    Network Director (IoT-FND) could allow an unauthenticated, remote attacker
    to conduct a cross-site request forgery (CSRF) attack and alter the data of
    existing users and groups on an affected device.

    The vulnerability is due to insufficient CSRF protections for the web-based
    management interface on an affected device. An attacker could exploit this
    vulnerability by persuading a user of the interface to follow a malicious
    link. A successful exploit could allow the attacker to perform arbitrary
    actions with the privilege level of the affected user. If the user has
    administrative privileges, the attacker could create a new, privileged
    account to obtain full control over the device interface.

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

Affected Products

  * Vulnerable Products

    This vulnerability affects the following Cisco products:

      + Connected Grid Network Management System, if running a software release
        prior to IoT-FND Release 3.0.
      + IoT Field Network Director, if running a software release prior to
        IoT-FND Release 4.1.1-6 or 4.2.0-123.

    Note: Cisco Connected Grid Network Management System and Cisco IoT Field
    Network Director are the same product. Prior to Release 3.0, this product
    was named Cisco Connected Grid Network Management System. As of Release
    3.0, this product is named Cisco IoT Field Network Director (IoT-FND).

    Products Confirmed Not Vulnerable

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

Workarounds

  * There are no workarounds that address this vulnerability.

Fixed Software

  * 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

    This vulnerability is fixed in Cisco IoT Field Network Director software
    4.1.1-6 and 4.2.0-123 and later releases.

    The software can be downloaded from the Software Center on Cisco.com by
    navigating to Products > Cloud and Systems Management > IoT Management and
    Automation > IoT Field Network Director.

  * 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.
