Summary

  * A vulnerability in the web-based UI of Cisco IP Phone 6800, 7800, and 8800
    Series with Multiplatform Firmware could allow an authenticated, remote
    attacker to perform a command injection and execute commands with the
    privileges of the web server.

    The vulnerability is due to insufficient input validation. An attacker
    could exploit this vulnerability by including arbitrary shell commands in a
    specific user input field.

    Cisco will release software updates that address this vulnerability. There
    are no workarounds that address this vulnerability.

    This advisory is available at the following link:

Affected Products

  * Vulnerable Products

    This vulnerability affects the following Cisco products running a
    Multiplatform Firmware release prior to Release 11.2(1):
      + IP Phone 6800 Series with Multiplatform Firmware
      + IP Phone 7800 Series with Multiplatform Firmware
      + IP Phone 8800 Series with Multiplatform Firmware

    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 will release 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 firmware Release 11.2(1), which will be
    available in August 2018.

    When they are available, the firmware updates can be downloaded from the
    Software Center on Cisco.com by navigating to Products > Collaboration
    Endpoints > IP Phones > IP Phones with Multiplatform Firmware.

Exploitation and Public Announcements

  * 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.
