This vulnerability is due to improper access controls on API endpoints when Cisco SD-WAN vManage Software is running in multi-tenant mode. An attacker with access to a device that is managed in the multi-tenant environment could exploit this vulnerability by sending a request to an affected API endpoint on the vManage system. A successful exploit could allow the attacker to gain access to sensitive information that may include hashed credentials that could be used in future attacks.","published":"2021-05-06T13:15:11.000Z","lastModified":"2026-06-17T03:31:58.000Z","status":"Modified","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},"cwe":["CWE-284"],"affected":["cisco/sd-wan vmanage"],"epss":{"score":0.00367,"percentile":0.30284,"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":"low","text":"Lower severity and a low EPSS score (0.37%).
