Summary

A cryptographic weakness exists in the Omada device adoption process.  During adoption, authentication credentials associated with site management are transmitted using a weak hashing algorithm that does not provide sufficient protection.

An attacker who successfully intercepts adoption-related authentication traffic may be able to recover valid credentials and gain unauthorized access to managed devices or controller-managed environments.
