CVE-2019-14473

Estado: ModificadaAlta (8.8)—

eQ-3 Homematic CCU2 and CCU3 use session IDs for authentication but lack authorization checks. Consequently, a valid guest level or user level account can create a new admin level account, read the service messages, clear the system protocol or modify/delete internal programs, etc. pp.
