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 "Solicitud de configuración de S1" sin el campo "TA compatibles" requerido para bloquear repetidamente el MME, lo que da como resultado la denegación de servicio.
