CVE-2025-30113
📋 TL;DR
The Forvia Hella HELLA Driving Recorder DR 820 dashcam's Android application contains hardcoded credentials that allow unauthorized access to device settings through ports 9091 and 9092. Attackers on the same network can exploit these cleartext credentials to modify dashcam configurations. All users of this dashcam model with the vulnerable Android app are affected.
