Comelit Multi-User Gateway for VIP System (model 1456B) firmware versions 2.9.1 and 2.10.0 fail to enforce server-side authorization on an administrative password-change function. An authenticated user level can invoke this function to overwrite the installer (administrator) account password.

Comelit Multi-User Gateway for VIP System (model 1456B) firmware versions 2.9.1 and 2.10.0 expose a network-accessible management interface that does not require authentication. Through this interface, sensitive device configuration data - including the Remote Configuration Password - can be read in cleartext by a remote, unauthenticated attacker.
