An attacker could exploit this vulnerability by sending crafted HTTPS requests to the AP file upload interface. A successful exploit could allow the attacker to upload files, perform path traversal, and execute arbitrary commands with root privileges.","published":"2025-05-07T18:15:39.000Z","lastModified":"2026-06-17T08:41:01.000Z","status":"Analyzed","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":10,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"},"cwe":["CWE-798"],"affected":["cisco/ios xe"],"epss":{"score":0.27488,"percentile":0.98059,"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":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 27.5%, higher than 98% of all known CVEs.
