CVE-2024-34463 BPL Medical Technologies CVE debrief

BPL Medical Technologies PWS-01-BT personal weighing scales transmit sensitive data via unencrypted Bluetooth Low Energy (BLE) packets, exposing user information to nearby eavesdroppers. The BLE communications lack encryption, authentication, and integrity protection, allowing passive interception and potential data manipulation within physical proximity. The vulnerability affects all firmware versions of the PWS-01-BT hardware (model IND/09/18/599) and the companion Be Well Android application through version 3.64. CISA published this advisory on September 10, 2024, after BPL Medical Technologies failed to respond to coordination requests. No patch is available; users must rely on physical proximity controls and contact vendor support for guidance.

Who should care

Healthcare facilities using BPL PWS-01-BT scales for patient monitoring, individuals using these devices for personal health tracking, and organizations with Bring Your Own Device (BYOD) policies allowing personal health devices on corporate networks.

Technical summary

The PWS-01-BT personal weighing scale broadcasts sensitive user data via BLE without encryption, authentication, or integrity checks. An attacker with physical proximity can passively capture weight measurements and potentially associated user identifiers. The adjacent network attack vector (AV:A) requires the attacker to be within Bluetooth radio range. No authentication is required for packet capture. The vulnerability stems from missing cryptographic protections in the BLE protocol implementation rather than a protocol-level BLE weakness.

Defensive priority

medium

Recommended defensive actions

  • Minimize use of affected weighing scales in public or semi-public spaces where unauthorized individuals may be within Bluetooth range (typically 10-100 meters)
  • Disable Bluetooth on mobile devices when not actively using the Be Well application to reduce exposure window
  • Contact BPL Medical Technologies customer support to request security updates or replacement guidance for affected devices
  • Monitor for unusual Bluetooth activity in environments where these devices are deployed
  • Consider alternative personal health devices with encrypted wireless communications for sensitive use cases

Evidence notes

CISA CSAF advisory ICSMA-24-254-01 documents unencrypted BLE transmission of sensitive data without authentication or integrity mechanisms. CVSS 3.1 score of 4.6 reflects adjacent network attack vector with low confidentiality and integrity impact.
