The vulnerability is due to an incorrect firewall rule on the device. The misconfiguration could allow traffic sent to the public interface of the device to be forwarded to the internal virtual network of the APIC-EM. An attacker that is logically adjacent to the network on which the public interface of the affected APIC-EM resides could leverage this behavior to gain access to services listening on the internal network with elevated privileges. 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-20171101-apicem Affected Products Vulnerable Products This vulnerability affects appliances or virtual devices running Cisco Application Policy Infrastructure Controller Enterprise Module prior to version 1.5. Products Confirmed Not Vulnerable No other Cisco products are currently 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: http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.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 upgrade 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: http://www.cisco.com/en/US/support/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 APIC-EM release 1.5 or later. The software can be downloaded from the Software Center on Cisco.com by navigating to Downloads > Home > Products > Cloud and Systems Management > Policy and Automation Controllers > Application Policy Infrastructure Controller Enterprise Module (APIC-EM) > APIC-EM Software Updates-1.5 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.
