CVE-2025-47855Network attack vector

Device configuration disclosure via crafted web requests

Published Jan 13, 2026 · Updated Jan 13, 2026

Information disclosure in Fortinet FortiFone 3.0.13 through 3.0.23 and 7.0.0 through 7.0.1 allows remote attackers to obtain device configurations. The FortiFone web portal returns the local device configuration when it processes crafted HTTP or HTTPS requests without authentication. Network access to the web portal is sufficient; disclosed configuration data can expose sensitive device and telephony settings, while no separate write capability is reported.
