CVE-2023-49261Network attack vector

Authentication token disclosure via login-page HTML

Published Jan 12, 2024 · Updated Oct 10, 2024

Information disclosure in Hongdian H8951-4G-ESP firmware before 2310271149 allows remote attackers to obtain tokenKey. The unauthenticated login page embeds this authorization value in its HTML source rather than keeping it server-side. Network access to the router management interface is sufficient, exposing authentication-related material without reported integrity or availability impact.
