Description

A certification validation weakness exists in communication between affected Omada devices and cloud controllers. Certificate identity verification does not adequately validate that a presented certificate corresponds to the expected cloud controller hostname, which may allow certificate validation protections to be bypassed under specific conditions. Successful exploitation may allow interception or modification of communication between affected devices and cloud controllers.
