CVE-2025-30115
📋 TL;DR
The Forvia Hella HELLA Driving Recorder DR 820 uses hardcoded default WiFi credentials (SSID and password 'qwertyuiop') that cannot be changed by users. This allows attackers to easily connect to the device's network and potentially access sensitive driving data or control functions. All users of this specific driving recorder model are affected.
