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 MicroDigital N-series cameras with firmware through 6400.0.8.5. The firmware update process is insecure, leading to remote code execution. The attacker can provide arbitrary firmware in a .dat file via a webparam?system&action=set&upgrade URI.

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

MicroDigital N-series cameras with firmware through 6400.0.8.5 have an insecure firmware update mechanism. The webparam?system&action=set&upgrade endpoint lacks proper authentication and validation, allowing attackers to upload arbitrary .dat firmware files and achieve remote code execution.

MitigationImplement authentication requirements for the firmware update endpoint and add cryptographic signature verification to ensure only legitimate, signed firmware can be installed. Consider also enforcing HTTPS for all management interfaces.

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 camera model
    Access the camera web interface or use the device's API to retrieve the model number. Check if the device is a Microdigital Mdc N4090, N4090w, or N2190v model.
    Affected if The device model is one of: Mdc N4090, Mdc N4090w, or Mdc N2190v.
  2. Check the firmware version
    Access the camera's admin panel or use the device's API to retrieve the firmware version. Look for a version field in the system information or status page.
    Affected if The installed firmware version is 6400.0.8.5 or lower.
  3. Test unauthenticated access to the update endpoint
    Attempt to access the URL path /webparam?system&action=set&upgrade directly without providing any login credentials. Observe if the endpoint responds or accepts requests.
    Affected if The endpoint responds without requiring authentication.
  4. Verify if HTTP is used for management
    Check if the camera web interface is accessible over HTTP (port 80) rather than only HTTPS. Attempt to connect to the device using HTTP.
    Affected if The management interface is accessible over unencrypted HTTP.

The device is affected if it is a Microdigital N4090, N4090w, or N2190v model running firmware version 6400.0.8.5 or lower, and the /webparam?system&action=set&upgrade endpoint is accessible without authentication.

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
Upgrade available Upgrade to a release after 6400.0.8.5
Interim mitigation

Implement authentication requirements for the firmware update endpoint and add cryptographic signature verification to ensure only legitimate, signed firmware can be installed. Consider also enforcing HTTPS for all management interfaces.
