CVE-2019-10119
eQ-3 HomeMatic CCU2 devices before 2.41.8 and CCU3 devices before 3.43.16 use session IDs for authentication but lack authorization checks. An attacker can obtain a session ID via an invalid login attempt to the RemoteApi account, aka HMCCU-154. This leads to automatic login as admin.
