      "value": "Apache Karaf allows monitoring of applications and the Java runtime by using the Java Management Extensions (JMX). JMX is a Java RMI based technology that relies on Java serialized objects for client server communication. Whereas the default JMX implementation is hardened against unauthenticated deserialization attacks, the implementation used by Apache Karaf is not protected against this kind of attack. The impact of Java deserialization vulnerabilities strongly depends on the classes that are available within the targets class path. Generally speaking, deserialization of untrusted data does always represent a high security risk and should be prevented. The risk is low as, by default, Karaf uses a limited set of classes in the JMX server class path. It depends of system scoped classes (e.g. jar in the lib folder)."

      "value": "Apache Karaf permite la monitorizaci\u00f3n de aplicaciones y del runtime de Java mediante el uso de las Extensiones de Administraci\u00f3n de Java (JMX). JMX es una tecnolog\u00eda basada en Java RMI que es basada en objetos serializados de Java para la comunicaci\u00f3n cliente-servidor. Mientras que la implementaci\u00f3n por defecto de JMX est\u00e1 reforzada contra ataques de deserializaci\u00f3n no autenticados, la implementaci\u00f3n usada por Apache Karaf no est\u00e1 protegida contra este tipo de ataques. El impacto de las vulnerabilidades de deserializaci\u00f3n de Java depende en gran medida de las clases disponibles en la ruta de clases del objetivo. En general, la deserializaci\u00f3n de datos no confiables siempre representa un alto riesgo de seguridad y debe ser prevenida. El riesgo es bajo ya que, por defecto, Karaf usa un conjunto limitado de clases en la ruta de clases del servidor JMX. Depende de las clases de \u00e1mbito del sistema (por ejemplo, jar en la carpeta lib)"
