CVE-2025-63292
Full vulnerability record from the local CVENow database.
Description
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.

"value": "Se descubrió que 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) y Freebox One (firmware = 4.7.x) exponían los identificadores IMSI de los suscriptores en texto plano durante la fase inicial de la autenticación EAP-SIM a través de la red ’FreeWifi_secure’. Durante el intercambio EAP-Response/Identity, el identificador completo de acceso a la red (NAI) del suscriptor, que incrusta el IMSI en bruto, se transmite sin cifrado, tunelización o seudonimización. Un atacante ubicado dentro del alcance de Wi-Fi (~100 metros) puede capturar pasivamente estas tramas sin requerir interacción del usuario o privilegios elevados. El IMSI divulgado permite el seguimiento de dispositivos, la correlación de suscriptores y el monitoreo a largo plazo de la presencia del usuario cerca de cualquier dispositivo Freebox que transmita. El proveedor reconoció la vulnerabilidad, y el servicio ’FreeWifi_secure’ está previsto que se desactive por completo antes del 1 de octubre de 2025."
