The vulnerability is due to insufficient validation of user-provided input. An attacker could exploit this vulnerability by logging in with a highly privileged user account and performing a sequence of specific user management operations that interfere with the underlying operating system. A successful exploit could allow the attacker to permanently degrade the functionality of the affected system.","published":"2018-10-05T14:29:04.000Z","lastModified":"2026-06-17T01:30:53.000Z","status":"Modified","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.0","score":4.9,"severity":"MEDIUM","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-20"],"affected":["cisco/enterprise network virtualization software"],"epss":{"score":0.01477,"percentile":0.73743,"date":"2026-10-27","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 (1.48%).
