CVE-2024-50381
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 · uneditedA vulnerability exists in Snap One OVRC cloud where an attacker can impersonate a Hub device and send requests to claim and unclaim devices. The attacker only needs to provide the MAC address of the targeted device and can make a request to unclaim it from its original connection and make a request to claim it.
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 confidenceThe Snap One OVRC cloud has an authentication bypass vulnerability where the claim/unclaim API relies solely on MAC address validation without additional verification. An attacker can spoof a Hub device's MAC address to impersonate it, allowing unauthorized claim and unclaim operations on any device in the system.

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 OVRC cloud usageDetermine if your organization uses Snap One's OVRC cloud service to manage smart home or automation devices. Check for any subscriptions or integrations with Snap One's cloud platform.Affected if You are a Snap One customer using OVRC cloud to manage Hub devices
-
Inventory Hub devicesReview your device inventory to identify any Hub devices (network hubs, controllers, or similar devices) registered in the OVRC cloud system.Affected if You have one or more Hub devices registered in OVRC cloud
-
Review ownership claim logsAccess OVRC cloud audit logs or device management console and examine claim/unclaim operation history. Look for ownership transfer events, particularly those occurring without documented approval from the previous owner.Affected if There are claim or unclaim operations in the logs that were not initiated by your organization or authorized personnel
-
Check for unauthorized ownership transfersCompare current device ownership records against known legitimate owners. Identify any Hub devices where ownership was transferred to unexpected or unknown accounts.Affected if Any Hub device shows ownership transferred to an account you do not recognize or did not authorize
-
Verify MAC address handlingIf you have access to OVRC API or system configuration, inspect how device authentication is performed. Confirm whether claim/unclaim requests rely solely on MAC address validation without additional cryptographic verification.Affected if The system accepts claim/unclaim requests based only on MAC address without requiring additional device authentication credentials
You are affected if you use Snap One's OVRC cloud to manage Hub devices and the system allows ownership claims without verifying device identity beyond the MAC address.

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 dataImplement multi-factor device authentication beyond MAC address verification, such as certificate-based authentication, cryptographic token validation, or device registration with challenge-response verification before allowing claim operations.
