{"id":"CVE-2025-63292","details":"Freebox v5 HD (firmware = 1.7.20), Freebox v5 Crystal (firmware = 1.7.20), Freebox v6 Révolution r1–r3 (firmware = 4.7.x), Freebox Mini 4K (firmware = 4.7.x), and Freebox One (firmware = 4.7.x) were discovered to expose subscribers' IMSI identifiers in plaintext during the initial phase of EAP-SIM authentication over the `FreeWifi_secure` network. During the EAP-Response/Identity exchange, the subscriber's full Network Access Identifier (NAI), which embeds the raw IMSI, is transmitted without encryption, tunneling, or pseudonymization. An attacker located within Wi-Fi range (~100 meters) can passively capture these frames without requiring user interaction or elevated privileges. The disclosed IMSI enables device tracking, subscriber correlation, and long-term monitoring of user presence near any broadcasting Freebox device. The vendor acknowledged the vulnerability, and the `FreeWifi_secure` service is planned for full deactivation by 1 October 2025.","modified":"2026-03-13T03:40:43.599385Z","published":"2025-11-17T19:16:20.037Z","references":[{"type":"WEB","url":"https://7h30th3r0n3.fr/the-vulnerability-that-killed-freewifi_secure/"},{"type":"EVIDENCE","url":"https://gist.github.com/7h30th3r0n3/1a0fadb19f1528e3d3f6bad9f680c3b0#file-cve-2025-63292-frebox-imsi-md"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"1.7.20"}]},{"events":[{"introduced":"0"},{"last_affected":"1.7.20"}]},{"events":[{"introduced":"0"},{"last_affected":"4.7.0"}]},{"events":[{"introduced":"0"},{"last_affected":"4.7.0"}]},{"events":[{"introduced":"0"},{"last_affected":"4.7.0"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-63292.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N"}]}
