Cisco FXOS Software and Firepower Threat Defense Software Command Injection

Priority:        High

Advisory ID:     cisco-sa-20191002-fxos-cmd-inject

First Published: 2019 October 2 16:00 GMT

Version 1.0:     Final

Workarounds:     No workarounds available



CVSS Score:


  o Multiple vulnerabilities in the CLI of Cisco FXOS Software and Cisco
    Firepower Threat Defense (FTD) Software could allow an authenticated, local
    attacker to execute commands on the underlying operating system (OS) with
    root privileges.

    These vulnerabilities are due to insufficient input validation. An attacker
    could exploit these vulnerabilities by including crafted arguments to
    specific CLI commands. A successful exploit could allow the attacker to
    execute commands on the underlying OS with root privileges.

Fixed Software

  o Cisco has released free software updates that address the vulnerabilities
    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:

    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

    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

    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
