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. All dashcams were shipped with the same default credentials of 12345678, which creates an insecure-by-default condition. For users who change their passwords, it's limited to 8 characters. These short passwords can be cracked in 8 hours via low-end commercial cloud resources.

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 ships with a hardcoded default password '12345678' for all devices, creating a critical insecure-by-default condition. Additionally, user-chosen passwords are limited to only 8 characters, which can be brute-forced in approximately 8 hours using low-end commercial cloud computing resources.

MitigationImmediately change the default password to a strong, unique credential; if the device firmware cannot support longer passwords, isolate the device on a restricted network segment and contact the vendor for a firmware update that removes the 8-character password limitation.

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
    Locate the dashcam in your inventory or network and confirm it is a Marbella KR8s Dashcam FF model. Check the device label, management interface, or DHCP lease logs for the device hostname or manufacturer identifier.
    Affected if The device is a Marbella KR8s Dashcam FF
  2. Check the firmware version
    Access the dashcam administration interface or check the device system information to determine the installed firmware version. Compare this against version 2.0.8.
    Affected if The firmware version is 2.0.8
  3. Test for the hardcoded default password
    Attempt to authenticate to the dashcam web interface or API using the username for the administrator account and the password '12345678'. Note: only perform this on devices you are authorized to test.
    Affected if Authentication succeeds with the password '12345678'
  4. Verify password length limitation
    Access the password change or account settings in the dashcam administration interface. Attempt to set a password longer than 8 characters to see if the interface rejects it or truncates it.
    Affected if The interface rejects or truncates passwords longer than 8 characters

You are affected if you have a Marbella KR8s Dashcam FF running firmware version 2.0.8 that either still uses the default password '12345678' or enforces an 8-character maximum password length.

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.

Mitigation

Immediately change the default password to a strong, unique credential; if the device firmware cannot support longer passwords, isolate the device on a restricted network segment and contact the vendor for a firmware update that removes the 8-character password limitation.
