A vulnerability in Cisco Digital Network Architecture (DNA) Center could allow an unauthenticated, adjacent attacker to bypass authentication and access critical internal services.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.73%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A vulnerability in Cisco Digital Network Architecture (DNA) Center could allow an unauthenticated, adjacent attacker to bypass authentication and access critical internal services. The vulnerability is due to insufficient access restriction to ports necessary for system operation. An attacker could exploit this vulnerability by connecting an unauthorized network device to the subnet designated for cluster services. A successful exploit could allow an attacker to reach internal services that are not hardened for external access.
