The issue is due to improper sanitization of user-supplied input in HTTP request parameters that describe filenames and pathnames. An attacker could exploit this vulnerability by using directory traversal techniques to submit a path to a desired file location. A successful exploit could allow the attacker to view system files on the targeted device, which may contain sensitive information.","published":"2018-10-17T22:29:00.000Z","lastModified":"2026-06-17T01:30:45.000Z","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-22"],"affected":["cisco/wireless lan controller software"],"epss":{"score":0.04638,"percentile":0.91671,"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 (4.64%).
