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 · unedited
An issue was discovered on Marbella KR8s Dashcam FF 2.0.8 devices. Once access is gained either by default, common, or cracked passwords, the video recordings (containing sensitive routes, conversations, and footage) are open for downloading by creating a socket to command port 7777, and then downloading video via port 7778 and audio via port 7779.

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 · high confidence

The Marbella KR8s Dashcam FF 2.0.8 exposes sensitive video and audio recordings through unauthenticated network ports after obtaining access via default, common, or cracked passwords. The device uses command port 7777, video download port 7778, and audio download port 7779, allowing attackers to exfiltrate footage containing sensitive routes, conversations, and visual data.

MitigationImmediately change default credentials and disable or firewall ports 7777-7779 if remote access is not required; if firmware updates are available from the vendor, apply them to address the hardcoded/default credential issue.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the device model
    Access the device web interface or check the device label/documentation to confirm it is a Marbella KR8s Dashcam FF
    Affected if The device is a Marbella KR8s Dashcam FF
  2. Check the firmware version
    Log into the device admin panel or check the system information page to determine the installed firmware version
    Affected if The firmware version is 2.0.8
  3. Verify port exposure
    Perform a network scan of the device IP address targeting TCP ports 7777, 7778, and 7779 using a tool like nmap (e.g., nmap -p 7777-7779 <device_ip>)
    Affected if Ports 7777, 7778, or 7779 are open and accessible from an untrusted network
  4. Test authentication on command port
    Connect to port 7777 (e.g., using netcat or telnet) and attempt to send commands without providing credentials
    Affected if The device accepts commands or provides access without authentication
  5. Check credential status
    Review the device configuration to determine if the default password remains unchanged or if common/weak passwords are in use
    Affected if The default password has not been changed or a weak/common password is configured

A user is affected if they have a Marbella KR8s Dashcam FF with firmware version 2.0.8 that has ports 7777-7779 exposed and uses default or weak credentials.
