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
A broken authorization vulnerability in Kiloview NDI N30 allows a remote unauthenticated attacker to deactivate user verification, giving them access to state changing actions that should only be initiated by administratorsThis issue affects Kiloview NDI N30 and was fixed in Firmware version later than 2.02.0246

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

The Kiloview NDI N30 contains a broken authorization vulnerability allowing unauthenticated remote attackers to deactivate user verification. By bypassing the authentication mechanism, attackers gain access to state-changing administrative functions that should require privileged credentials. This represents a complete bypass of access controls with severe impact to confidentiality and integrity.

MitigationUpgrade Kiloview NDI N30 firmware to version higher than 2.02.0246. If immediate patching is not possible, isolate the device behind a firewall or VPN to limit untrusted network exposure.

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 device model
    Access the device web interface or check the device label/marketing materials to confirm the model is Kiloview NDI N30 encoder. This vulnerability affects only this specific model.
    Affected if The device is not a Kiloview NDI N30 encoder, then it is not affected by this specific CVE.
  2. Determine the installed firmware version
    Log into the device web interface and navigate to System Settings or About page to view the firmware version. Alternatively, check via the device's command-line interface if available. Compare the version to 2.02.0246.
    Affected if The firmware version is 2.02.0246 or earlier, or the version cannot be confirmed, then the device may be affected.
  3. Verify network exposure of the device
    Check the device's network configuration to determine if the web management interface is accessible from untrusted networks. Review firewall rules and network segmentation around the device.
    Affected if The device management interface is exposed directly to the internet or untrusted networks, then the unauthenticated exploitation path is present.
  4. Test authentication enforcement for administrative actions
    Attempt to access administrative functions or state-changing endpoints without providing credentials. If the device allows unauthenticated access to deactivate user verification or perform admin actions, the vulnerability is present.
    Affected if Administrative functions or authentication settings can be modified without valid credentials, the device is affected by the authorization bypass.

A device is affected if it is a Kiloview NDI N30 encoder running firmware version 2.02.0246 or earlier, with its management interface accessible to untrusted networks, and administrative functions can be executed without authentication.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade Kiloview NDI N30 firmware to version higher than 2.02.0246. If immediate patching is not possible, isolate the device behind a firewall or VPN to limit untrusted network exposure.

Recommended fix Moderate confidence

Any firmware version later than 2.02.0246 (check Kiloview support for latest stable release)

  1. Access the Kiloview NDI N30 device administration interface via web browser
  2. Navigate to the firmware settings or system update section
  3. Check the current firmware version to confirm it is 2.02.0246 or earlier
  4. Download the latest firmware update from the official Kiloview support website (www.kiloview.com)
  5. Upload the firmware file through the device web interface or appropriate update mechanism
  6. Wait for the firmware update process to complete and the device to reboot
  7. Verify the new firmware version is installed successfully
  8. Test that user authentication is functioning properly after the update
Caveat Firmware updates may temporarily interrupt device operation; ensure proper power supply and do not interrupt the update process
