The vulnerability is due to incorrect parsing of a specific TACACS attribute received in the TACACS response from the remote TACACS server. An attacker could exploit this vulnerability by authenticating via TACACS to the GUI on the affected device. A successful exploit could allow an attacker to create local user accounts with administrative privileges on an affected WLC and execute other commands that are not allowed from the CLI and should be prohibited.","published":"2018-10-17T22:29:00.000Z","lastModified":"2026-06-17T01:30:44.000Z","status":"Modified","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-264"],"affected":["cisco/wireless lan controller software","cisco/wireless lan controller"],"epss":{"score":0.03163,"percentile":0.8793,"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":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (3.16%).
