Improper Input Validation

Summary

Improper Input Validation, Improper Control of Generation of Code ('Code Injection') vulnerability in Apache ActiveMQ, Apache ActiveMQ Broker, Apache ActiveMQ All. An authenticated attacker can use the admin web console page to construct a malicious broker name that bypasses name validation and includes an xbean binding that can later be used by a VM transport to load a remote Spring XML application. The attacker can then use the DestinationView mbean to send a message that triggers VM transport creation, referencing the malicious broker name, which can lead to loading the malicious Spring XML context file. 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: prior to 5.19.6, from 6.0.0 prior to 6.2.5; Apache ActiveMQ Broker: prior to 5.19.6, from 6.0.0 prior to 6.2.5; Apache ActiveMQ All: prior to 5.19.6, from 6.0.0 prior to 6.2.5. Users are recommended to upgrade to version 6.2.5 or 5.19.6, which fixes the issue.
