CVE-2025-63292
3.5 · LOWOverview
CVE-2025-63292 is a low-severity vulnerability affecting freebox v5_hd_firmware. It was published on November 17, 2025 and has a CVSS 3.1 base score of 3.5 (LOW).
This vulnerability has a CVSS 3.1 base score of 3.5, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical 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.
Remediation
Check the references section for vendor advisories and patches from freebox. Update v5_hd_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
