Authentication Bypass in Omada Devices via Embedded Certificates

Executive Summary

This vulnerability involves Omada devices using shared embedded certificates across deployments to establish trust between controllers and managed devices. If an attacker obtains these certificates, they can impersonate trusted controllers or devices and intercept communications.

Useful 0 Not Useful 0

Detection Guidance

Detection involves checking for unauthorized or unexpected Omada controller or device communications. Monitor network traffic for unusual TLS handshakes or certificate exchanges. Inspect Omada controller logs for anomalies in device authentication. Use network scanning tools to identify Omada devices and verify their certificates are not shared or compromised.
