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. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities. This advisory is available at the following link: https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/ cisco-sa-20191002-fxos-cmd-inject Affected Products o Vulnerable Products These vulnerabilities affect Cisco FXOS Software and Cisco FTD Software releases when running on the following platforms: Cisco Firepower 1000 Series Appliances Cisco Firepower 2100 Series Appliances Cisco Firepower 4100 Series Appliances Cisco Firepower 9300 Series Appliances Products Confirmed Not Vulnerable Only products listed in the Vulnerable Products section of this advisory are known to be affected by these vulnerabilities. Workarounds o There are no workarounds that address these vulnerabilities. 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: 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.
