Summary
  • (es) Las versiones de Open5GS MME anteriores a la 2.6.4 contienen una aserción que se puede activar de forma remota a través de un paquete ASN.1 mal formado a través de la interfaz S1AP. Un atacante puede enviar un mensaje de "Respuesta de configuración de contexto inicial" sin el campo "MME_UE_S1AP_ID" requerido para bloquear repetidamente el MME, lo que da como resultado la denegación de servicio.
