CVE-2020-27373Public exploit

Device control via unauthenticated plaintext BLE commands

Published Apr 7, 2022 · Updated Jul 9, 2026

Plaintext command handling in Dr Trust USA iCheck Connect BP Monitor BP Testing 118 1.2.1 allows attackers to control the device over BLE. The BLE GATT interface permits an unpaired client to connect, enumerate exposed characteristics, and issue commands in plaintext. Exploitation requires physical proximity and Bluetooth access; public records do not identify the exact device operations exposed.
