Descriptions

A regression has been introduced in the commit preventing JMX re-bind. By passing an empty environment map to RMIConnectorServer, instead of the map that contains the authentication credentials, it leaves ActiveMQ open to the following attack: https://docs.oracle.com/javase/8/docs/technotes/guides/management/agent.html "A remote client could create a javax.management.loading.MLet MBean and use it to create new MBeans from arbitrary URLs, at least if there is no security manager. In other words, a rogue remote client could make your Java application execute arbitrary code." Mitigation: Upgrade to Apache ActiveMQ 5.15.13

Se ha introducido una regresión en el commit que evita que JMX vuelva a vincularse. Al pasar un mapa de entorno vacío hacia RMIConnectorServer, en lugar del mapa que contiene las credenciales de autenticación, deja ActiveMQ abierto al siguiente ataque: https://docs.oracle.com/javase/8/docs/technotes/guides/management/ agent.html. " Un cliente remoto podría crear un MBean javax.management.loading.MLet y usarlo para crear nuevos MBeans a partir de URL arbitrarias, al menos si no existe un administrador de seguridad. En otras palabras, un cliente remoto fraudulento podría hacer que la aplicación ejecute código arbitrario". Mitigación: actualización a Apache ActiveMQ versión 5.15.13
