On eQ-3 HomeMatic CCU2 devices before 2.41.8 and CCU3 devices before 3.43.16, automatic login configuration (aka setAutoLogin) can be achieved by continuing to use a session ID after a logout, aka HMCCU-154.

eQ-3 HomeMatic CCU2 devices before 2.41.8 and CCU3 devices before 3.43.15 use session IDs for authentication but lack authorization checks. An attacker can obtain a session ID via the user authentication dialogue, aka HMCCU-153. This leads to automatic login as admin.

eQ-3 HomeMatic CCU2 devices before 2.41.9 and CCU3 devices before 3.43.16 have buffer overflows in the ReGa ise GmbH HTTP-Server 2.0 component, aka HMCCU-179. This may lead to remote code execution.
