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
Binardat 10G08-0800GSM network switch firmware version V300SP10260209 and prior contain hard-coded administrative credentials that cannot be changed by users. Knowledge of these credentials allows full administrative access to the device.

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 Binardat 10G08-0800GSM network switch firmware versions V300SP10260209 and prior contains hardcoded administrative credentials embedded in the firmware binary that cannot be modified or changed by administrators, allowing any attacker with knowledge of these credentials to gain full administrative (root) access to the device.

MitigationImplement strict network access controls and segmentation to limit exposure of the affected device, and contact Binardat for a patched firmware release that removes the hardcoded credentials or provides proper credential management capabilities.

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 CLI, web interface, or physical label to confirm the model is Binardat 10G08-0800GSM
    Affected if The device is not a Binardat 10G08-0800GSM switch
  2. Check the installed firmware version
    Use the command 'show version' in the device CLI, or check the firmware information page in the web management interface
    Affected if The firmware version cannot be determined or accessed
  3. Compare firmware version to the affected range
    Compare the obtained firmware version against V300SP10260209 - versions at or below this value are affected
    Affected if Firmware version is V300SP10260209 or any earlier version (for example, V300SP10123456)

The device is affected if it is a Binardat 10G08-0800GSM switch running firmware version V300SP10260209 or any earlier version.

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 data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Implement strict network access controls and segmentation to limit exposure of the affected device, and contact Binardat for a patched firmware release that removes the hardcoded credentials or provides proper credential management capabilities.
