CVE-2025-30126
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 Marbella KR8s Dashcam FF 2.0.8 devices. Via port 7777 without any need to pair or press a physical button, a remote attacker can disable recording, delete recordings, or even disable battery protection to cause a flat battery to essentially disable the car from being used. During the process of changing these settings, there are no indications or sounds on the dashcam to alert the dashcam owner that someone else is making those changes.
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 Marbella KR8s Dashcam FF 2.0.8 has an unauthenticated network service on port 7777 that allows remote attackers to disable recording, delete recordings, or disable battery protection without any user notification. The lack of authentication or pairing requirements enables anyone with network access to the device to issue these commands silently.

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 device model and firmware versionAccess the dashcam settings interface or check the device's system information to confirm it is a Marbella KR8s Dashcam FF and note the installed firmware versionAffected if The device is a Marbella KR8s Dashcam FF running firmware version 2.0.8
-
Verify port 7777 is accessible on the deviceUse a network scanning tool such as nmap or netcat to check if port 7777 is open and listening on the dashcam's IP addressAffected if Port 7777 is open and accepting connections on the device
-
Test unauthenticated access to the port 7777 serviceEstablish a raw TCP connection to port 7777 on the device (e.g., using netcat or telnet) and observe whether the service accepts commands or returns a prompt without requiring any authentication, pairing, or credentialsAffected if The service on port 7777 responds or accepts input without any authentication or pairing requirement
-
Confirm command execution capabilityIf connected to port 7777, issue a test command to disable recording, delete a recording, or disable battery protection and verify the command is executed without any audible or visual alert on the deviceAffected if Commands to disable recording, delete recordings, or disable battery protection execute silently without user notification
A user is affected if they have a Marbella KR8s Dashcam FF on firmware version 2.0.8 with port 7777 exposed and the service accepts unauthenticated commands that execute silently.

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 dataImplement authentication for the port 7777 service and add audible/visual alerts when settings are changed remotely. Consider network segmentation to limit exposure of the dashcam's network interface.
