Remediation/Mitigation Strategy: CVE-2025-30113 - Forvia Hella DR 820 Hardcoded Credentials

This document outlines the remediation and mitigation strategy for CVE-2025-30113, a vulnerability found in the Forvia Hella DR 820 Driving Recorder.

1. Vulnerability Description:

  • CVE ID: CVE-2025-30113
  • Affected Product: Forvia Hella HELLA Driving Recorder DR 820
  • Description: The Android application for the Hella DR 820 dashcam contains hardcoded credentials for accessing device settings via ports 9091 and 9092. These credentials are stored in cleartext within the APK file.

2. Severity:

  • CVSS Score: 9.8 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H (Network, Low Attack Complexity, No Privileges Required, No User Interaction, Unchanged Scope, Confidentiality Impact High, Integrity Impact High, Availability Impact High)
  • Explanation: The vulnerability allows a remote, unauthenticated attacker to gain full control of the dashcam due to the easily accessible credentials. This includes potentially accessing sensitive recordings, modifying settings, disabling the device, or using the device as a pivot point for further network attacks.

3. Known Exploit:

  • The vulnerability is considered exploitable since the credentials are hardcoded and likely easily extracted from the APK file.
  • An attacker with network access to the dashcam (e.g., through a compromised Wi-Fi network) can connect to ports 9091 and 9092 and use the hardcoded credentials to authenticate and gain unauthorized control.

4. Remediation Strategy:

The ultimate solution is a firmware/software update from Forvia Hella that addresses the hardcoded credentials. This update should:

  • Remove Hardcoded Credentials: Replace the hardcoded credentials with a more secure authentication mechanism. This could involve:
    • A unique, dynamically generated password per device.
    • Public-key cryptography.
    • Requiring user configuration of credentials.
  • Secure the Communication Channel: Encrypt communication channels used by the application. HTTPS should be used for any sensitive data transfer.
  • Implement Access Controls: Restrict access to sensitive functions to authorized users only after proper authentication.

Action Items for Forvia Hella:

  1. Develop and Release a Firmware/Software Update: This is the most critical step. Prioritize developing and releasing an update that addresses the root cause of the vulnerability (the hardcoded credentials).
  2. Vulnerability Disclosure: Publicly disclose the vulnerability and the available patch.
  3. Secure Development Practices: Implement secure coding practices to prevent similar issues in future products. This includes avoiding hardcoded credentials, using strong encryption, and performing regular security audits.

5. Mitigation Strategy (While awaiting a patch):

Since a firmware update may take time, the following mitigation measures should be implemented to reduce the risk:

  • Network Segmentation: Isolate the dashcam on a separate network segment or VLAN with limited access to other resources. This limits the potential impact of a compromise.
  • Firewall Rules: Implement firewall rules to restrict access to ports 9091 and 9092 to only authorized IP addresses or devices, or block all incoming connections to these ports.
  • Strong Wi-Fi Security: Ensure the Wi-Fi network the dashcam is connected to is secured with a strong password and uses WPA3 encryption. Disable WPS (Wi-Fi Protected Setup) if possible, as it’s known to be vulnerable.
  • Monitor Network Traffic: Monitor network traffic to and from the dashcam for suspicious activity.
  • Change Default Administrator Passwords (If Possible): If the dashcam has a web interface or other means of administration, change the default password immediately. Even if this isn’t related to the hardcoded credentials in the APK, it’s a general security best practice. However, since the vulnerability lies within the application itself this may not be applicable.
  • User Awareness: Educate users about the vulnerability and the importance of network security. Warn them to avoid connecting the dashcam to untrusted Wi-Fi networks.
  • Consider Disabling or Replacing the Dashcam: As a last resort, consider disabling the dashcam or replacing it with a more secure alternative, especially if it’s used in a sensitive environment.

6. Long-Term Security:

  • Regular Security Audits: Conduct regular security audits and penetration testing on the dashcam’s firmware and software.
  • Vulnerability Disclosure Program: Implement a vulnerability disclosure program to encourage security researchers to report vulnerabilities responsibly.
  • Software Bill of Materials (SBOM): Generate and maintain an SBOM for the dashcam’s firmware and software to track the dependencies and identify potential vulnerabilities in third-party components.

7. Disclaimer:

This remediation/mitigation strategy is based on the information available at the time of writing. It is recommended to consult with security experts and refer to official advisories from Forvia Hella for the most up-to-date information and guidance.
