The vulnerability exists because an insecure method is used to mask certain passwords on the web-based management interface. An attacker could exploit this vulnerability by looking at the raw HTML code that is received from the interface. A successful exploit could allow the attacker to obtain some of the passwords configured throughout the interface.","published":"2020-09-04T03:15:11.000Z","lastModified":"2026-06-17T03:18:34.000Z","status":"Modified","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-200","CWE-522"],"affected":["cisco/asyncos"],"epss":{"score":0.00875,"percentile":0.58716,"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 (0.88%).
