CVE-2020-13425Public exploit

Battery exhaustion via unauthenticated Bluetooth alarm writes

Published May 23, 2020 · Updated Aug 4, 2024

Missing authorization in TrackR devices through 2020-05-06 allows physically proximate attackers to exhaust the battery via the Beep feature. The Bluetooth Low Energy alarm characteristic accepts the standard Beep value without authentication or an authorization check. An attacker within roughly ten meters can repeatedly activate the beeper until the battery is depleted, leaving the tracker unable to operate.
