Descriptions

An issue in the Certificate Authenticated Session Establishment (CASE) protocol for establishing secure sessions between two devices, as implemented in the Matter protocol versions before Matter 1.1 allows an attacker to replay manipulated CASE Sigma1 messages to make the device unresponsive until the device is power-cycled.

Un problema en el protocolo de establecimiento de sesión autenticado por certificado (CASE) para establecer sesiones seguras entre dos dispositivos, tal como se implementó en las versiones del protocolo Matter anteriores a Matter 1.1, permite a un atacante reproducir mensajes CASE Sigma1 manipulados para que el dispositivo no responda hasta que se encienda ciclado.
