      "value": "An issue was discovered in the captive portal in OpenNDS before version 10.1.3. get_query in http_microhttpd.c does not validate the length of the query string of GET requests. This leads to a stack-based buffer overflow in versions 9.x and earlier, and to a heap-based buffer overflow in versions 10.x and later. Attackers may exploit the issue to crash OpenNDS (Denial-of-Service condition) or to inject and execute arbitrary bytecode (Remote Code Execution)."

Esto provoca un desbordamiento del b\u00fafer basado en pila en las versiones 9.x y anteriores, y un desbordamiento del b\u00fafer basado en pila en las versiones 10.x y posteriores. Los atacantes pueden aprovechar el problema para bloquear OpenNDS (condici\u00f3n de denegaci\u00f3n de servicio) o para inyectar y ejecutar c\u00f3digo de bytes arbitrario (ejecuci\u00f3n remota de c\u00f3digo)."
