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
The SunPower PVS6's BluetoothLE interface is vulnerable due to its use of hardcoded encryption parameters and publicly accessible protocol details. An attacker within Bluetooth range could exploit this vulnerability to gain full access to the device's servicing interface. This access allows the attacker to perform actions such as firmware replacement, disabling power production, modifying grid settings, creating SSH tunnels, altering firewall settings, and manipulating connected devices.

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 · high confidence

The SunPower PVS6's BluetoothLE interface uses hardcoded encryption parameters and exposes protocol details publicly. An attacker within Bluetooth range can intercept communications and gain full servicing interface access, enabling firmware replacement, power production control, grid setting modification, SSH tunnel creation, firewall changes, and device manipulation.

MitigationReplace hardcoded encryption parameters with dynamically generated keys, implement proper authentication for the BluetoothLE interface, and apply firmware updates that address the weak cryptographic implementation.

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. Confirm device model is SunPower PVS6
    Locate the physical device or check device inventory/documentation for the model number PVS6. This vulnerability affects only this specific inverter/model.
    Affected if The device is a SunPower PVS6 unit
  2. Verify BluetoothLE is enabled
    Access the device management interface or check Bluetooth settings on the PVS6. Use Bluetooth scanner tools (such as nRF Connect or BLE Explorer) to detect if the PVS6 is broadcasting as a BLE device.
    Affected if BluetoothLE is actively broadcasting and discoverable
  3. Check firmware version
    Access the PVS6 web interface, mobile app, or use manufacturer diagnostic tools to retrieve the installed firmware version. Compare against any SunPower firmware release notes for your model.
    Affected if Firmware version matches the affected range for this CVE (no specific version range provided, so any unpatched version is potentially vulnerable)
  4. Inspect BluetoothLE service configuration
    Connect to the PVS6 via BluetoothLE and enumerate services/characteristics. Look for services that indicate servicing interface access (often labeled as debug, service, or admin functions). Check if authentication is required or if access is open.
    Affected if Servicing interface is accessible without proper authentication or uses known hardcoded parameters

A defender is affected if they have a SunPower PVS6 device with BluetoothLE enabled and the firmware has not been updated to address hardcoded encryption weaknesses in the BLE interface.
