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.","published":"2019-06-20T03:15:12.000Z","lastModified":"2026-06-17T02:29:27.000Z","status":"Modified","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.0","score":9.3,"severity":"CRITICAL","vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N"},"cwe":["CWE-668"],"affected":["cisco/digital network architecture center"],"epss":{"score":0.00729,"percentile":0.53963,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.73%).
