CVE-2025-9696

Device takeover via shared Bluetooth encryption key

Published Sep 2, 2025 · Updated Sep 2, 2025

Hardcoded credentials in SunPower PVS6 2025.06 build 61839 and earlier allow physically proximate attackers to control it via Bluetooth. The Bluetooth LE protocol encrypts servicing requests with AES-128-CBC using one preshared key across devices and an all-zero initialization vector. Bluetooth range plus knowledge of the protocol and shared key permits reading system data, changing network and grid settings, disabling power production, and initiating signed firmware updates.
