An attacker can use the 'class' property of the JSON request sent to the CLDB to influence the JSON library's decision on which Java class this JSON request is deserialized to. By doing so, the attacker can force the MapR CLDB to construct a URLClassLoader which loads a malicious Java class from a remote path and instantiate this object in the MapR CLDB, thus executing arbitrary code on the machine running the MapR CLDB and take over the cluster. By switching to the newer Jackson library and ensuring that all incoming JSON requests are only deserialized to the same class that it was serialized from, the vulnerability is fixed. This vulnerability affects the entire MapR core platform."}, {"lang": "es", "value": "Se presenta una vulnerabilidad de ejecuci\u00f3n de c\u00f3digo remota en el c\u00f3digo de MapR CLDB, espec\u00edficamente en el framework JSON que es usado en el c\u00f3digo de CLDB que maneja el inicio de sesi\u00f3n y la emisi\u00f3n de tickets. Un atacante puede usar la propiedad \"class\" de la petici\u00f3n JSON enviada al CLDB para influir en la decisi\u00f3n de la biblioteca JSON sobre a qu\u00e9 clase de Java es deserializada esta petici\u00f3n JSON. Al hacerlo, el atacante puede forzar el MapR CLDB para construir un URLClassLoader que carga una clase Java maliciosa desde una ruta remota e instanciar este objeto en el MapR CLDB, ejecutando as\u00ed un c\u00f3digo arbitrario en la m\u00e1quina que ejecuta el MapR CLDB y tomar el control del cl\u00faster .
