The vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading an authenticated user of the interface to follow a crafted link. A successful exploit could allow the attacker to perform arbitrary actions on a targeted device via a web browser and with the privileges of the user. This vulnerability affects Cisco IP Phone 8800 Series products running a SIP Software release prior to 11.0(5) for Wireless IP Phone 8821 and 8821-EX; and 12.5(1)SR1 for the IP Conference Phone 8832 and the rest of the IP Phone 8800 Series. Cisco IP Conference Phone 8831 is not affected.","published":"2019-03-22T20:29:00.000Z","lastModified":"2026-06-17T02:29:15.000Z","status":"Modified","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.0","score":8.8,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"cwe":["CWE-352"],"affected":["cisco/ip phone 8821 firmware","cisco/ip phone 8821-ex firmware","cisco/ip conference phone 8832 firmware","cisco/ip phone 8800 firmware"],"epss":{"score":0.00698,"percentile":0.52848,"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":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.70%).
