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. A buffer overflow in the action parameter leads to remote code execution in the context of the nobody 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

A buffer overflow vulnerability in the 'action' parameter of MicroDigital N-series IP cameras (firmware up to 6400.0.8.5) allows unauthenticated remote attackers to execute arbitrary code. The exploit executes in the context of the low-privilege 'nobody' account, which may limit immediate system impact but could enable further privilege escalation.

MitigationIdentify all affected MicroDigital N-series cameras on the network, verify firmware versions, and apply any available vendor firmware updates. If no patch exists, isolate cameras behind a firewall or VLAN to limit attack surface.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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 MicroDigital N-series camera model
    Access the camera web interface and look for the model name (N4090, N4090w, N2190v) in the device info page, or query the device via SNMP/OID for system description
    Affected if Device model is not one of the listed N-series models (N4090, N4090w, N2190v)
  2. Retrieve firmware version
    In the camera web interface, navigate to System or Device Info section to view firmware version, or use SNMP query to check firmware/revision OIDs
    Affected if Unable to retrieve firmware version or device does not have a web interface
  3. Compare installed firmware to affected version
    Compare the retrieved firmware version against the vulnerable range: versions <= 6400.0.8.5
    Affected if Firmware version is 6400.0.8.5 or lower
  4. Verify network exposure of web interface
    Check if the camera HTTP/HTTPS ports (typically 80/443) are accessible from untrusted networks, or perform a port scan to confirm open HTTP service
    Affected if Camera web interface is exposed to untrusted networks without firewall protection

You are affected if you have a MicroDigital N4090, N4090w, or N2190v camera running firmware version 6400.0.8.5 or lower, and the web interface is network-accessible.

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

Identify all affected MicroDigital N-series cameras on the network, verify firmware versions, and apply any available vendor firmware updates. If no patch exists, isolate cameras behind a firewall or VLAN to limit attack surface.
