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

Detail

Apache ActiveMQ is a widely used messaging server that is employed in enterprises to facilitate message-oriented middleware. Organizations integrate ActiveMQ into their applications to ensure robust, reliable, and high-performance message transfers between distributed systems. Due to its open-source nature, developers and IT professionals rely on ActiveMQ for seamless integration in various environments, spanning from cloud applications to embedded systems. The software's feature-rich capabilities include topic conversations, scalability, and cross-platform compatibility, making it preferable for real-time data processing. However, like many complex systems, ActiveMQ is subject to vulnerabilities, necessitating frequent updates and patches to maintain secure operations.

The detected vulnerability in Apache ActiveMQ pertains to Remote Code Execution, which may arise from improper input validation. If exploited, it allows authenticated users to execute arbitrary codes within the Java Virtual Machine hosting ActiveMQ. By manipulating the Jolokia JMX-HTTP bridge, attackers can introduce and run malicious scripts, resulting in potential system compromise. The vulnerability specifically targets the open interfaces that facilitate the execution of commands without appropriate security checks. It allows adversaries to craft URIs that use ActiveMQ's internal functions for unauthorized operations.

By leveraging such gaps, attackers can fully control the underlying computing resources, endangering the integrity and confidentiality of the systems in place. Neglecting this vulnerability might lead to devastating outcomes, including data theft and unauthorized access. There are impactful consequences should this Remote Code Execution vulnerability be exploited. It can lead to a complete system takeover by unauthorized actors, who can deploy malicious software, manipulate data, or listen in on private conversations. The compromise of ActiveMQ systems can undermine an organization's data privacy and result in substantial reputational and financial damages. Reference measurements and thorough handling of system permissions are critical to mitigating these severe effects. A successful RCE attack also facilitates further attacks and cyber espionage activities.

Solution Advice
  • Upgrade to Apache ActiveMQ version 5.19.5 or 6.2.3 or newer, as these versions have addressed the vulnerability.
  • Regularly review and update access policies for Jolokia JMX-HTTP bridges to prevent unauthorized operations.
  • Implement strong authentication measures to restrict access to ActiveMQ management consoles and endpoints.
  • Conduct routine security assessments and penetration testing to identify and remedy potential exposure points in your network infrastructure.
  • Ensure proper network segmentation and firewall rules to limit incoming requests to management interfaces.
