The vulnerability is due to insufficient authorization of certain API functions. An attacker could exploit this vulnerability by sending a crafted request to the API using low-privileged credentials. A successful exploit could allow the attacker to perform arbitrary actions through the REST API with administrative privileges.","published":"2020-07-31T00:15:13.000Z","lastModified":"2026-06-17T03:18:09.000Z","status":"Modified","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-285","CWE-863"],"affected":["cisco/data center network manager"],"epss":{"score":0.02042,"percentile":0.81021,"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 (2.04%).
