Hardcoded TLS private key and certificate in firmware in Kiloview N30 2.02.246 allows malicious adversary to do a Mann-in-the-middle attack via the network

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 N30 encoder firmware version 2.02.246 contains a hardcoded TLS private key and certificate embedded in the firmware image. Because the same private key is present in all devices running this firmware version, an attacker who extracts the key from one device can decrypt TLS traffic or impersonate any other device on the network, enabling man-in-the-middle attacks.

MitigationContact Kiloview for a firmware update that replaces hardcoded certificates with dynamically generated or device-unique certificates; in the interim, isolate affected devices on a dedicated network segment and monitor for signs of TLS interception.

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. Confirm device model
    Identify if the target device is a Kiloview N30 encoder by checking the device label, web interface, or system information page
    Affected if The device is not a Kiloview N30 encoder (unaffected model)
  2. Check firmware version
    Access the device web interface or CLI and retrieve the firmware version number; compare against 2.02.246
    Affected if Firmware version is exactly 2.02.246 (exact match to affected version)
  3. Locate TLS certificate storage
    Examine the firmware image or device filesystem for embedded certificate files (typically .pem, .crt, .key, or .p12 extensions)
    Affected if Hardcoded certificate and private key files exist in the firmware or device storage
  4. Compare certificates across devices
    Extract the TLS certificate from this device and compare it to certificates extracted from other Kiloview N30 devices running the same firmware version
    Affected if Multiple devices share an identical certificate and private key (non-unique certificates)
  5. Inspect TLS handshake details
    Capture and analyze TLS traffic or inspect the device TLS configuration to verify if the same certificate is used for all encrypted sessions
    Affected if The device uses a static, non-unique certificate for TLS connections

The device is affected if it is a Kiloview N30 encoder running firmware version 2.02.246 that contains a hardcoded TLS private key and certificate identical across all devices.
