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.
This vulnerability carries a CRITICAL severity rating with a CVSS v3.1 score of 9.3, indicating it requires adjacent network access with relatively low complexity without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), for affected systems. Impacting 1 product from cisco organizations running these solutions should prioritize assessment and patching.
First disclosed in 2019, this vulnerability was reported during a period defined by widespread IoT adoption challenges, mobile security concerns, and the emergence of advanced persistent threat (APT) techniques. Contemporary mitigation strategies focused on secure development practices and third-party component vetting.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For cisco's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
