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. SQL injection vulnerabilities exist in 13 forms that are reachable through HTTPD. An attacker can, for example, create an admin account.

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

SQL injection vulnerabilities in 13 HTTP-accessible forms on MicroDigital N-series IP cameras (firmware through 6400.0.8.5) allow remote unauthenticated attackers to inject arbitrary SQL commands. This can result in authentication bypass, enabling attackers to create administrative accounts and gain full device control.

MitigationApply vendor firmware patch if available; otherwise isolate cameras behind a firewall or VLAN to restrict HTTP management access to trusted networks only.

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's web interface and look for the model number in the system information or status page, or check the device label/sticker
    Affected if The model is NOT one of: Mdc N4090, Mdc N4090w, or Mdc N2190v (these are the only affected models)
  2. Check the firmware version
    In the camera web interface, navigate to the firmware or system info page to view the installed firmware version number
    Affected if The firmware version is 6400.0.8.5 or lower (versions above 6400.0.8.5 are not affected)
  3. Confirm HTTP management interface is accessible
    Attempt to access the camera's IP address on port 80 (HTTP) or port 443 (HTTPS) from a browser
    Affected if The HTTP/HTTPS management interface is reachable (this is required for the SQL injection to be exploitable)
  4. Verify network exposure
    Determine if the camera HTTP port is accessible from untrusted networks by checking firewall rules, NAT configurations, or port forwarding settings
    Affected if The camera HTTP interface is exposed directly to the internet or untrusted networks (this indicates higher risk exposure for unauthenticated attacks)

You are affected if you have a MicroDigital Mdc N4090, N4090w, or N2190v camera running firmware version 6400.0.8.5 or lower, with the HTTP management interface accessible to the network where the attacker resides.
