CVE-2020-13702 (GCVE-0-2020-13702)

Vulnerability from cvelistv5 – Published: 2020-06-11 18:16 – Updated: 2024-08-04 12:25

Summary

The Rolling Proximity Identifier used in the Apple/Google Exposure Notification API beta through 2020-05-29 enables attackers to circumvent Bluetooth Smart Privacy because there is a secondary temporary UID. An attacker with access to Beacon or IoT networks can seamlessly track individual device movement via a Bluetooth LE discovery mechanism.
