Additionally there is a bit signaling the module to auto start. When these bits are set for any of the three modules and the device is moved into a run state, a fault is triggered."}, {"lang": "es", "value": "Existe una vulnerabilidad explotable de control de acceso en las funcionalidades data, program y function file de Allen Bradley Micrologix 1400 Series B FRN, en versiones 21.2 y anteriores.
