Descriptions

In Matter (aka connectedhomeip or Project CHIP) through 1.4.0.0, the WriteAcl function deletes all existing ACL entries first, and then attempts to recreate them based on user input. If input validation fails during decoding, the process stops, and no entries are restored by access-control-server.cpp, i.e., a denial of service.

En Matter (también conocido como connectedhomeip o Project CHIP) hasta la versión 1.4.0.0, la función WriteAcl elimina primero todas las entradas de ACL existentes y luego intenta volver a crearlas en función de la entrada del usuario. Si la validación de la entrada falla durante la decodificación, el proceso se detiene y access-control-server.cpp no restaura ninguna entrada, es decir, se produce una denegación de servicio.
