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.","published":"2025-11-17T19:16:20.000Z","lastModified":"2026-06-17T09:53:01.000Z","status":"Analyzed","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":3.5,"severity":"LOW","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N"},"cwe":["CWE-319"],"affected":["freebox/v5 hd firmware","freebox/v5 crystal firmware","freebox/v6 revolution firmware","freebox/mini 4k firmware","freebox/one firmware"],"epss":{"score":0.00114,"percentile":0.01489,"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":"low","text":"Lower severity and a low EPSS score (0.11%).
