Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-30115 is a vulnerability in the Forvia Hella HELLA Driving Recorder DR 820, where default credentials cannot be changed by users. The device employs a fixed default SSID and password ("qwertyuiop"), and the SSID is continuously broadcast. This configuration, tied to CWE-259 (Use of Hard-coded Password), enables unauthorized access to the device network. The issue carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) and was published on 2025-03-18.
Any remote attacker within wireless range can exploit this vulnerability by connecting to the broadcast SSID using the unchanging default password, requiring no privileges, user interaction, or complex conditions. Exploitation provides unauthorized network access to the device, with potential for high impacts on confidentiality, integrity, and availability.
