Severity: important
Affected versions:
- Apache ActiveMQ Broker (org.apache.activemq:activemq-broker) before 5.19.4
- Apache ActiveMQ Broker (org.apache.activemq:activemq-broker) 6.0.0 before
6.2.3
- Apache ActiveMQ (org.apache.activemq:activemq-all) before 5.19.4
- Apache ActiveMQ (org.apache.activemq:activemq-all) 6.0.0 before 6.2.3
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: .
Users are recommended to upgrade to version 5.19.5 or 6.2.3, which fixes the
issue.
