CVE-2025-30113 in HELLA Driving Recorder DR 820
Summary
by MITRE • 03/18/2025
An issue was discovered on the Forvia Hella HELLA Driving Recorder DR 820. Hardcoded Credentials exist in the APK for Ports 9091 and 9092. The dashcam's Android application contains hardcoded credentials that allow unauthorized access to device settings through ports 9091 and 9092. These credentials, stored in cleartext, can be exploited by an attacker who gains access to the dashcam's network.

The vulnerability identified in the Forvia Hella HELLA Driving Recorder DR 820 represents a critical security flaw that undermines the device's integrity and exposes sensitive operational capabilities. This dashcam system, designed for vehicle monitoring and data recording, contains hardcoded authentication credentials within its Android application package that are accessible through network ports 9091 and 9092. The presence of such credentials in cleartext format creates a fundamental weakness in the device's security architecture, as these hardcoded values are typically embedded during the development phase and remain unchanged throughout the device's operational lifecycle.
The technical implementation of this vulnerability stems from improper credential management practices within the application's source code and configuration files. When developers embed authentication credentials directly into the application code rather than implementing secure dynamic credential retrieval mechanisms, they create persistent access points that remain accessible to anyone who can analyze the application's components. The specific ports 9091 and 9092 serve as entry points for unauthorized administrative access to the device's configuration interfaces, allowing attackers to manipulate recording settings, access stored video data, modify system parameters, and potentially compromise the device's operational integrity. This flaw aligns with CWE-798, which specifically addresses the use of hardcoded credentials, and represents a direct violation of secure coding practices that should prevent such exposures in production systems.
The operational impact of this vulnerability extends beyond simple unauthorized access to encompass significant risks for vehicle operators and data privacy. Attackers who can gain network access to the dashcam device can exploit these hardcoded credentials to modify recording schedules, disable recording functions, access sensitive video footage, and potentially interfere with the device's primary purpose of monitoring vehicle activities. The vulnerability creates persistent backdoor access points that remain functional regardless of user password changes or system updates, making it particularly dangerous for fleet management applications where multiple devices may be deployed across various vehicles. From an attacker's perspective, this represents a low-effort, high-impact vector that requires minimal reconnaissance to exploit, as the credentials are readily available within the application's binary components.
The security implications of this vulnerability align with several ATT&CK framework techniques including T1078 for valid accounts and T1566 for credential harvesting, as the hardcoded credentials can be extracted through static analysis of the APK file. Network-based attacks exploiting ports 9091 and 9092 could enable lateral movement within vehicle networks, particularly in fleet environments where multiple dashcams might be interconnected. The vulnerability also raises concerns regarding data integrity and confidentiality, as unauthorized access could lead to manipulation of recorded evidence or exposure of sensitive information. Organizations deploying these devices should consider implementing network segmentation and access controls to limit exposure, while the manufacturer should provide firmware updates that eliminate the hardcoded credentials and implement proper authentication mechanisms. This vulnerability demonstrates the critical importance of secure credential management practices and highlights the risks associated with embedded systems that fail to implement proper authentication security measures.
