The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. Impacted is confidentiality, integrity, and availability. CVE summarizes:

A vulnerability in the management interface of Cisco Application Policy Infrastructure Controller (APIC) software could allow an unauthenticated, adjacent attacker to gain unauthorized access on an affected device. The vulnerability is due to a lack of proper access control mechanisms for IPv6 link-local connectivity imposed on the management interface of an affected device. An attacker on the same physical network could exploit this vulnerability by attempting to connect to the IPv6 link-local address on the affected device. A successful exploit could allow the attacker to bypass default access control restrictions on an affected device. Cisco Application Policy Infrastructure Controller (APIC) devices running versions prior to 4.2(0.21c) are affected.

The bug was discovered 03/06/2019. The weakness was published 03/11/2019 as cisco-sa-20190306-apic-ipv6 as confirmed advisory (Website). The advisory is available at tools.cisco.com. This vulnerability is handled as CVE-2019-1690 since 12/06/2018. Access to the local network is required for this attack. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1068 by the MITRE ATT&CK project.

The vulnerability was handled as a non-public zero-day exploit for at least 5 days. During that time the estimated underground price was around $5k-$25k.
