Description
A cryptographic weakness exists in affected Omada devices where site credentials are protected using a legacy hashing algorithm that does not provide sufficient protection. An attacker who obtains access to stored credential data may be able to recover valid credentials to gain unauthorized access to affected devices or management environments.
