This vulnerability exists because a password policy check is incomplete at the time a password is changed at server side using the API. An attacker could exploit this vulnerability by sending a specially crafted API request to the affected device. A successful exploit could allow the attacker to change their own password to a value that does not comply with the configured strong authentication requirements.","published":"2021-08-04T18:15:08.000Z","lastModified":"2026-06-17T03:31:59.000Z","status":"Modified","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"},"cwe":["CWE-255","CWE-521"],"affected":["cisco/connected mobile experiences"],"epss":{"score":0.00748,"percentile":0.54684,"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 (0.75%).
