An authentication weakness was identified in Omada Controllers, Gateways and Access Points, controller-device adoption due to improper handling of random values

Overview

An authentication weakness was identified in Omada Controllers, Gateways and Access Points, controller-device adoption due to improper handling of random values. Exploitation requires advanced network positioning and allows an attacker to intercept adoption traffic and forge valid authentication through offline precomputation, potentially exposing sensitive information and compromising confidentiality.
