CVE-2026-34197
Full vulnerability record from the local CVENow database.
Description
Improper Input Validation, Improper Control of Generation of Code ('Code Injection') vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ. Apache ActiveMQ Classic exposes the Jolokia JMX-HTTP bridge at /api/jolokia/ on the web console. The default Jolokia access policy permits exec operations on all ActiveMQ MBeans (org.apache.activemq:*), including BrokerService.addNetworkConnector(String) and BrokerService.addConnector(String). An authenticated attacker can invoke these operations with a crafted discovery URI that triggers the VM transport's brokerConfig parameter to load a remote Spring XML application context using ResourceXmlApplicationContext. Because Spring's ResourceXmlApplicationContext instantiates all singleton beans before the BrokerService validates the configuration, arbitrary code execution occurs on the broker's JVM through bean factory methods such as Runtime.exec(). This issue affects Apache ActiveMQ Broker: before 5.19.4, from 6.0.0 before 6.2.3; Apache ActiveMQ All: before 5.19.4, from 6.0.0 before 6.2.3; Apache ActiveMQ: before 5.19.4, from 6.0.0 before 6.2.3. Users are recommended to upgrade to version 5.19.4 or 6.2.3, which fixes the issue

La política de acceso predeterminada de Jolokia permite operaciones exec en todos los MBeans de ActiveMQ (org.apache.activemq:*), incluyendo BrokerService.addNetworkConnector(String) y BrokerService.addConnector(String).\n\nUn atacante autenticado puede invocar estas operaciones con una URI de descubrimiento manipulada que activa el parámetro brokerConfig del transporte VM para cargar un contexto de aplicación XML de Spring remoto utilizando ResourceXmlApplicationContext. Debido a que ResourceXmlApplicationContext de Spring instancia todos los beans singleton antes de que BrokerService valide la configuración, se produce la ejecución de código arbitrario en la JVM del broker a través de métodos de fábrica de beans como Runtime.exec().\nEste problema afecta a Apache ActiveMQ Broker: anterior a 5.19.4, desde 6.0.0 anterior a 6.2.3; Apache ActiveMQ: .\n\nSe recomienda a los usuarios actualizar a la versión 5.19.4 o 6.2.3, que corrige el problema."
