JVNDB-2024-000086

Vulnerability from jvndb - Published: 2024-08-22 04:51 - Updated:2024-08-29 03:23

Severity

4.2 (Medium) - cvssV3_0 - CVSS:3.0/AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N

Summary

Multiple Safie products vulnerable to improper server certificate verification

Details

Multiple Safie products are vulnerable to improper server certificate verification (CWE-295). The product can be operated via port 11029/TCP and Bluetooth, and its communications are AES encrypted. The product user can obtain the encryption key from the cloud server based on the device-specific information. The user who has obtained the device-specific information can directly operate the device (even if it is not owned by the user). Taizoh Tsukamoto of Mitsui Bussan Secure Directions, Inc. reported these vulnerabilities to IPA. JPCERT/CC coordinated with the developer under Information Security Early Warning Partnership.
