The vulnerability of microprogrammed software in logic controllers for building and facility control systems from Schneider Electric—such as spaceLYnk, Wiser for KNX (formerly homeLYnk), and FellerLYnk—is related to the lack of authentication for critical functions. This allows attackers to alter the configuration of the system.
