CVE-2023-0864

Configuration disclosure via plaintext BLE communication

Published May 17, 2023 · Updated Jan 22, 2025

Cleartext transmission in ABB Terra AC wallbox affected firmware allows physically proximate attackers to read configuration data over BLE. The BLE channel exchanges wallbox configuration data without encryption, exposing its contents to passive eavesdropping. Physically proximate attackers must remain within BLE range while a legitimate user configures or uses the device; the disclosed data can expose configuration settings.
