Cisco Security Advisory: Cisco Application Policy Infrastructure Controller Enterprise Module Unauthorized Access Vulnerability
Advisory ID: cisco-sa-20171101-apicem
Revision: 1.0
For Public Release: 2017 November 1 16:00 GMT
Last Updated: 2017 November 1 16:00 GMT
CVE ID(s): CVE-2017-12262
CVSS Score v(3): 8.8 CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
+———————————————————————
Summary
=======
A vulnerability within the firewall configuration of the Cisco Application Policy Infrastructure Controller Enterprise Module (APIC-EM) could allow an unauthenticated, adjacent attacker to gain privileged access to services only available on the internal network of the device.
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.
