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 Incorrect Access Control issue was discovered on MicroDigital N-series cameras with firmware through 6400.0.8.5 because any valid cookie can be used to make requests as an admin.

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

MicroDigital N-series IP cameras with firmware through 6400.0.8.5 contain an incorrect access control vulnerability where any valid authentication cookie (regardless of user privilege level) can be used to perform administrative actions. The system fails to properly validate that the cookie belongs to an admin user before granting elevated privileges.

MitigationUpdate camera firmware to a patched version if available. If no patch exists, restrict network access to cameras via firewall rules or network segmentation to limit exposure to untrusted users.

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

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 camera model
    Log into the camera web interface or check device documentation to confirm the exact model number is one of: Mdc N4090, Mdc N4090w, or Mdc N2190v
    Affected if Camera model is not one of the listed affected models - you are likely not affected
  2. Check firmware version
    Access the camera web interface, typically under Settings > System > Firmware or About page, to find the installed firmware version number
    Affected if Firmware version is 6400.0.8.5 or lower - you may be affected
  3. Verify admin privilege validation
    Log in with a non-administrator user account and attempt to access or execute an administrative function (such as modifying system settings, user management, or firmware update). Observe whether the action is denied or allowed
    Affected if A non-admin user can successfully perform admin-level actions using only a valid cookie - you are affected by this vulnerability
  4. Test cookie reuse behavior
    Capture an authentication cookie from a standard user session, then use that cookie to make a direct HTTP request to an administrative endpoint (e.g., /admin/settings or similar). Check if the request succeeds without additional privilege verification
    Affected if A valid cookie from a low-privilege user can be reused to execute administrative operations - the access control flaw is present

If the camera model matches one of the affected Mdc N4090/N4090w/N2190v units and runs firmware version 6400.0.8.5 or lower, AND a non-admin user can perform admin actions, then the environment is affected by CVE-2019-14705.

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

Update camera firmware to a patched version if available. If no patch exists, restrict network access to cameras via firewall rules or network segmentation to limit exposure to untrusted users.
