App - Sistema

APLICACIONES - SISTEMA. Aquí los retos a superar se basan en debilidades debidas a errores de programación en ciertos lenguajes de alto nivel (desbordamiento de buffer, corrupción de memoria, ...)

Facilitamos los identificadores de conexión para cada reto. El objetivo es obtener los derechos suplementarios explotando debilidades de programas y obtener la contraseña que te permitirá validar la prueba.

Requisitos previos:

  • Dominar GDB.
  • Tener bases de lenguaje ensamblador.
  • Conocer el lenguaje C.
