Summary
  • (es) FTP Navigator 8.03 contiene una vulnerabilidad de desbordamiento de pila que permite a los atacantes ejecutar código arbitrario sobrescribiendo los registros del Manejador de Excepciones Estructurado (SEH). Los atacantes pueden crear una carga útil maliciosa que desencadena un desbordamiento de búfer cuando se pega en el cuadro de texto Custom Command, lo que permite la ejecución remota de código y el lanzamiento de la calculadora como prueba de concepto.
