CVE-2025-30116 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. Remotely Dumping of Video Footage and the Live Video Stream can occur. It allows remote attackers to access and download recorded video footage from the SD card via port 9091. Additionally, attackers can connect to port 9092 to stream the live video feed by bypassing the challenge-response authentication mechanism. This exposes sensitive location and personal data.

The CVE-2025-30116 vulnerability affects the Forvia Hella HELLA Driving Recorder DR 820, a device designed for vehicle video surveillance and data recording. This security flaw represents a critical exposure in automotive telematics and driver monitoring systems that operate in the connected vehicle ecosystem. The vulnerability stems from insufficient authentication mechanisms and improper access controls within the device's network services, creating an attack surface that adversaries can exploit without requiring physical access or sophisticated credentials. The device's design fails to implement proper network segmentation and authentication protocols, allowing unauthorized remote access to sensitive video data that could include personal information, location data, and potentially confidential operational details.
The technical implementation of this vulnerability involves two distinct attack vectors that operate through specifically designated network ports. Port 9091 serves as an entry point for remote dumping of video footage stored on the device's SD card, enabling attackers to download recorded video content without proper authorization. This represents a failure in access control mechanisms and data protection measures that should prevent unauthorized data extraction from storage devices. Port 9092 provides access to live video streaming capabilities, which bypasses the challenge-response authentication mechanism that should normally protect the device's real-time video feed. This dual vulnerability creates a complete surveillance exposure where attackers can both access historical data and monitor current activities, fundamentally undermining the device's intended security posture and privacy protections.
The operational impact of this vulnerability extends beyond simple data exposure to encompass significant privacy and security implications for vehicle operators and passengers. The device's video feeds contain sensitive location information that can reveal personal travel patterns, home addresses, workplace locations, and other confidential data that adversaries could exploit for stalking, identity theft, or targeted attacks. The vulnerability particularly affects the automotive cybersecurity landscape by demonstrating how connected vehicle systems can fail to implement basic network security controls. This exposure creates risks for corporate fleets, individual vehicle owners, and potentially law enforcement agencies that rely on such devices for safety monitoring. The vulnerability also highlights the broader challenge of securing embedded automotive systems that often lack proper security architecture and authentication mechanisms.
This vulnerability aligns with multiple cybersecurity frameworks and threat classifications including CWE-287 for improper authentication and CWE-312 for exposure of sensitive information. The attack pattern follows typical adversarial behavior described in MITRE ATT&CK framework under T1041 for Exfiltration Over Command and Control Channel and T1566 for Phishing. The device's failure to implement proper network security controls creates an attack surface that allows for persistent monitoring and data collection, representing a significant risk to personal privacy and potentially violating data protection regulations such as GDPR, CCPA, and other privacy legislation. The vulnerability's severity is compounded by the fact that it affects automotive devices that are increasingly connected to corporate networks and cloud services, creating additional attack vectors and potential escalation paths.
Recommended mitigations for this vulnerability include immediate firmware updates from the manufacturer to implement proper authentication mechanisms and access controls, network segmentation to isolate the device from critical corporate networks, and implementation of network monitoring to detect unauthorized access attempts. Organizations should consider disabling unnecessary network services and ports, implementing strong authentication requirements for any remote access, and establishing regular security assessments of connected vehicle systems. The vulnerability underscores the importance of security-by-design principles in automotive systems and highlights the need for comprehensive security testing of embedded devices before deployment in vehicle environments. Additionally, security teams should implement network access controls and monitoring solutions specifically designed to detect and prevent unauthorized access to vehicle telematics and surveillance systems.
