Unauthenticated controller modification and service interruption
Published Jul 1, 2026 · Updated Jul 1, 2026
Authentication bypass in Delta Electronics AS228T 1.14 and earlier allows remote attackers to modify controller state over a network. Delta Electronics has not disclosed the affected service, alternate path, or request operation that omits authentication. Exploitation requires no credentials or user interaction but has high complexity and can modify or interrupt the controller.
