CVE-2024-50381 Overview
CVE-2024-50381 is a missing authentication vulnerability [CWE-306] in the Snap One OVRC cloud platform. Attackers can impersonate a Hub device and issue claim and unclaim requests against arbitrary devices. Exploitation requires only the Media Access Control (MAC) address of the targeted device. An attacker can unclaim a device from its legitimate owner and then claim it under attacker control. The flaw resides in the cloud service itself, so any internet-connected attacker can reach the vulnerable endpoint. The vulnerability affects integrated control systems commonly deployed in residential and commercial environments.
Critical Impact
Remote attackers can hijack OVRC-managed devices by submitting the device MAC address, transferring ownership without authentication.
Affected Products
- Snap One OVRC cloud platform
- OVRC-managed Hub devices
- Endpoint devices claimed through OVRC cloud

Technical Details for CVE-2024-50381
Vulnerability Analysis
The OVRC cloud accepts claim and unclaim requests without verifying that the requester is the legitimate Hub device. The service trusts a MAC address supplied in the request as the device identity. An attacker who knows or guesses a target MAC address can submit a forged request that the cloud processes as authoritative. The request first unclaims the device from its current owner, then re-claims it under the attacker's account. Once claimed, the attacker gains the management capabilities that OVRC exposes for that device class. This breaks the ownership and control model that downstream integrators rely on for remote management.
Root Cause
The root cause is missing authentication for a critical function [CWE-306]. The cloud endpoint does not require cryptographic proof of device identity before honoring claim state changes. MAC addresses are not secrets and are often discoverable through network reconnaissance, packaging, or device labels. Treating the MAC address as both identity and authentication collapses the trust boundary.
Attack Vector
The attack vector is network based with no privileges or user interaction required. An attacker enumerates or guesses MAC addresses of OVRC-managed devices. The attacker then submits crafted HTTPS requests to the OVRC cloud that mimic legitimate Hub traffic. The cloud accepts the impersonated requests and reassigns the targeted device. No physical access to the device or its local network is required.
No verified exploit code is published. See the CISA ICS Advisory ICSA-23-136-01 for related technical context on the OVRC platform.
Detection Methods for CVE-2024-50381
Indicators of Compromise
- Unexpected unclaim events on OVRC-managed devices followed by claim events from unfamiliar accounts
- Loss of remote management access to previously enrolled devices
- OVRC notification emails referencing account changes that the legitimate owner did not initiate
- Devices appearing offline in the original integrator dashboard while remaining powered and online locally
Detection Strategies
- Audit OVRC account activity logs for claim and unclaim events that do not correlate with planned deployments or service work
- Correlate device MAC inventory against current OVRC ownership records to identify unauthorized transfers
- Monitor outbound network traffic from Hub devices for anomalies that suggest cloud-side ownership has changed
Monitoring Recommendations
- Establish a baseline of authorized OVRC account holders and review ownership reports on a recurring schedule
- Forward OVRC notification emails to a monitored mailbox or ticketing system for review
- Track device claim state changes as a security-relevant event in any centralized logging platform
How to Mitigate CVE-2024-50381
Immediate Actions Required
- Contact Snap One support to confirm whether managed devices have been subject to unauthorized claim or unclaim events
- Reclaim any devices that have been transferred to unknown accounts and reset their cloud associations
- Restrict disclosure of device MAC addresses in documentation, photos, and customer communications
- Review OVRC account membership and remove inactive or unnecessary user accounts
Patch Information
No vendor patch identifier is listed in the public CVE record. Remediation depends on server-side changes within the Snap One OVRC cloud, which are deployed by the vendor rather than installed by customers. Consult Snap One directly for the current status of fixes and any required client-side updates.
Workarounds
- Treat device MAC addresses as sensitive inventory data and limit their exposure
- Maintain an offline record of device ownership so unauthorized transfers can be identified quickly
- Subscribe to OVRC account notifications and respond immediately to any unexpected claim state change
- Where feasible, isolate OVRC-managed devices on dedicated network segments to limit downstream impact if cloud ownership is hijacked
