CVE-2017-8866
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 · uneditedElemental Path's CogniToys Dino smart toys through firmware version 0.0.794 share a fixed small pool of hardcoded keys, allowing a remote attacker to use a different Dino device to decrypt VoIP traffic between a child's Dino and remote server.
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 confidenceThe CogniToys Dino smart toys through firmware version 0.0.794 contain a fixed pool of hardcoded encryption keys embedded in the firmware. An attacker with access to a different Dino device can extract these shared keys and use them to decrypt VoIP communications transmitted between a child's Dino toy and the remote server.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify firmware versionAccess the device settings or administrative interface to view the current firmware version. This may be visible in the companion app, device settings menu, or through a system information command if SSH/telnet access is available.Affected if The firmware version is 0.0.794 or earlier.
-
Extract and inspect firmware binaryIf firmware extraction is possible (through device hardware interfacing, OTA update interception, or firmware file analysis), search the binary for cryptographic key material. Look for patterns such as static encryption keys, symmetric key arrays, or RSA private key headers embedded in the firmware image.Affected if Hardcoded encryption keys or key material are found embedded in the firmware binary.
-
Verify VoIP feature usageMonitor network traffic between the Dino device and remote servers, or check device configuration to determine if VoIP communication is enabled. This may involve inspecting network logs, checking active connections on ports typically used for VoIP (SIP/RTP ports), or reviewing the device feature settings.Affected if VoIP communications are transmitted between the Dino toy and remote servers.
The device is affected if it runs firmware version 0.0.794 or earlier and uses VoIP functionality with the embedded hardcoded encryption keys.

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 dataUpdate firmware to version 0.0.795 or later which should implement unique per-device cryptographic keys instead of shared hardcoded keys, and conduct a security review of the key management implementation.
