CVE-2025-30116
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Forvia Hella HELLA Driving Recorder DR 820 contains an authentication bypass vulnerability that allows remote attackers to access recorded video footage from the SD card via port 9091 and stream live video via port 9092 by circumventing the built-in challenge-response authentication mechanism. This exposes sensitive location data and personal information captured by the device.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the HELLA Driving Recorder DR 820 on the networkScan the network for devices with manufacturer signature 'Hella' or 'Forvia' or model 'DR 820'. Use network scanning tools (such as nmap, Angry IP Scanner, or network device discovery) to find devices on the local network. Check DHCP logs, router device lists, or network topology documents for evidence of this specific device.Affected if The device with model identifier DR 820 or Hella driving recorder is found on the network.
-
Check if port 9091 is open and accessibleRun a port scan against suspected devices targeting port 9091. Command example: nmap -p 9091 <target-ip>. Also verify the service banner if available. This port handles access to recorded video footage from the SD card.Affected if Port 9091 returns as open and accepts connections.
-
Check if port 9092 is open and accessibleRun a port scan against suspected devices targeting port 9092. Command example: nmap -p 9092 <target-ip>. Also verify the service banner if available. This port handles live video streaming.Affected if Port 9092 returns as open and accepts connections.
-
Verify network accessibility of vulnerable portsDetermine if ports 9091 and 9092 are reachable from network segments that are not trusted. Check firewall rules, ACLs, and router configurations to see if these ports are exposed to untrusted networks, guest networks, or the internet. Use commands such as netstat, firewall-cmd, or iptables to inspect listening services and their binding addresses.Affected if Ports 9091 or 9092 are accessible from untrusted network segments or the internet.
-
Confirm firmware version is affectedAccess the device administration interface or check device documentation to determine the firmware version. Since all versions are affected, any firmware version present confirms exposure. If possible, log into the device web interface or check /proc/version via telnet/ssh if available.Affected if Any firmware version is confirmed to be installed (all versions are affected).
A user is affected if a HELLA Driving Recorder DR 820 device is present on the network with ports 9091 or 9092 exposed to untrusted network segments, as the authentication bypass allows unauthenticated access to sensitive video and location data.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataNetwork-level controls such as firewall rules to restrict access to ports 9091 and 9092, or network segmentation to isolate the device from untrusted networks, should be implemented as immediate mitigations while coordinating with the vendor for a firmware update to patch the authentication bypass.
