Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
BPL Personal Weighing Scale PWS-01BT IND/09/18/599 devices send sensitive information in unencrypted BLE packets. (The packet data also lacks authentication and integrity protection.)

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The BPL Personal Weighing Scale PWS-01BT transmits sensitive user data (weight/health measurements) over Bluetooth Low Energy without encryption. Additionally, the BLE communication lacks authentication, allowing any nearby BLE device to potentially interact with the scale, and lacks integrity protection, meaning transmitted data could be modified without detection.

MitigationAvoid using this device for sensitive health data until a firmware update is available from BPL; contact the vendor for patched firmware or consider replacing with a device that supports encrypted BLE communications.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the device model
    Inspect the physical device or packaging for the model number BPL Personal Weighing Scale PWS-01BT. Check product documentation or the BLE device name advertised over Bluetooth.
    Affected if The device is a BPL PWS-01BT scale
  2. Verify BLE advertising is active
    Use a BLE scanner app or tool (such as nRF Connect, BLE Explorer, or hcitool lescan) to detect if the scale is broadcasting BLE advertisements.
    Affected if The scale is actively broadcasting over BLE and is discoverable
  3. Test for BLE authentication requirement
    Attempt to connect to the scale via BLE using a generic BLE client without completing any pairing or authentication handshake. Observe if a connection is established without credentials.
    Affected if Connection is established without requiring PIN, passkey, or other authentication
  4. Sniff BLE traffic for encryption
    Use a BLE sniffer (such as Wireshark with BLE adapter, BTVS, or similar) to capture packets transmitted by the scale during use. Examine the ATT/GATT data for plaintext weight measurements or health data.
    Affected if Sensitive data (weight, health metrics) is transmitted in plaintext without encryption layer
  5. Check for data integrity protection
    Analyze captured BLE packets for the presence of message authentication codes, signatures, or sequence numbers that would detect tampering. Inject modified packets and verify if the device rejects or accepts them.
    Affected if Modified packets are accepted without detection or validation failure

A user is affected if they own a BPL PWS-01BT scale that transmits weight data over unencrypted, unauthenticated BLE and lacks integrity checks.
