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 SSRF issue was discovered in HTTPD on MicroDigital N-series cameras with firmware through 6400.0.8.5 via FTP commands following a newline character in the uploadfile field.

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 confidence

A Server-Side Request Forgery (SSRF) vulnerability exists in the HTTPD component of MicroDigital N-series IP cameras. The flaw allows injection of arbitrary FTP commands via a newline character in the uploadfile field, enabling attackers to make the device's HTTP server perform unauthorized requests to internal or external resources.

MitigationApply vendor firmware updates when available; if no patch exists, replace affected devices. As an immediate compensating control, network segment the cameras to restrict their ability to connect to internal resources.

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
    Log into the device web interface or check the device label to confirm the exact model number (Mdc N4090, N4090w, or N2190v).
    Affected if The model is NOT one of the three listed affected models.
  2. Check the firmware version
    Access the camera's web interface, typically at the '/system info' or '/status' page, or use the manufacturer's discovery tool to retrieve the firmware version string.
    Affected if The firmware version is GREATER than 6400.0.8.5 (the device is NOT affected if version > 6400.0.8.5).
  3. Verify HTTPD service accessibility
    Attempt to access the camera's HTTP server on the default port (usually 80) from a trusted network location to confirm the web service is running.
    Affected if The HTTP service is not accessible (the vulnerability cannot be exploited if the service is unreachable).
  4. Check if the uploadfile parameter endpoint is exposed
    Review the camera's web interface for any file upload functionality, particularly related to FTP configuration or firmware upload features.
    Affected if No upload-related endpoints exist or are accessible.

The device is affected only if it is a Microdigital Mdc N4090, N4090w, or N2190v model running firmware version 6400.0.8.5 or lower AND its HTTP service with upload functionality is network-accessible.
