La API de Kafka UI permite a los usuarios conectarse a diferentes corredores de Kafka especificando su direcci\u00f3n de red y puerto. Como caracter\u00edstica independiente, tambi\u00e9n brinda la capacidad de monitorear el desempe\u00f1o de los corredores de Kafka conect\u00e1ndose a sus puertos JMX. JMX se basa en el protocolo RMI, por lo que es inherentemente susceptible a ataques de deserializaci\u00f3n. Un atacante potencial puede aprovechar esta caracter\u00edstica conectando el backend de la interfaz de usuario de Kafka a su propio agente malicioso. Esta vulnerabilidad afecta las implementaciones donde ocurre una de las siguientes situaciones: 1. La propiedad dynamic.config.enabled est\u00e1 configurada en la configuraci\u00f3n. No est\u00e1 habilitado de forma predeterminada, pero se sugiere habilitarlo en muchos tutoriales para Kafka UI, incluido su propio README.md. O 2. un atacante tiene acceso al cl\u00faster de Kafka que se est\u00e1 conectando a la interfaz de usuario de Kafka. En este escenario, el atacante puede aprovechar esta vulnerabilidad para ampliar su acceso y ejecutar c\u00f3digo tambi\u00e9n en la interfaz de usuario de Kafka. En lugar de configurar un puerto JMX leg\u00edtimo, un atacante puede crear un detector RMI que devuelva un objeto serializado malicioso para cualquier llamada RMI. En el peor de los casos, podr\u00eda conducir a la ejecuci\u00f3n remota de c\u00f3digo, ya que Kafka UI tiene las cadenas de dispositivos necesarias en su classpath. Este problema puede provocar la ejecuci\u00f3n remota de c\u00f3digo posterior a la autenticaci\u00f3n. Esto es particularmente peligroso ya que Kafka-UI no tiene la autenticaci\u00f3n habilitada de forma predeterminada. Este problema se solucion\u00f3 en la versi\u00f3n 0.7.2. Se recomienda a todos los usuarios que actualicen. No se conocen workarounds para esta vulnerabilidad.
