Ce mail provient de l'extérieur, restons vigilants ===================================================================== CERT-Renater Note d'Information No. 2026/VULN425 _____________________________________________________________________ DATE : 24/04/2026 HARDWARE PLATFORM(S): / OPERATING SYSTEM(S): Systems running Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ versions prior to 5.19.6, 6.2.5. ===================================================================== https://activemq.apache.org/security-advisories.data/CVE-2026-40466-announcement.txt https://activemq.apache.org/security-advisories.data/CVE-2026-41043-announcement.txt https://activemq.apache.org/security-advisories.data/CVE-2026-41044-announcement.txt _____________________________________________________________________ Severity: important Affected versions: - Apache ActiveMQ Broker (org.apache.activemq:activemq-broker) before 5.19.6 - Apache ActiveMQ Broker (org.apache.activemq:activemq-broker) 6.0.0 before 6.2.5 - Apache ActiveMQ All (org.apache.activemq:activemq-all) before 5.19.6 - Apache ActiveMQ All (org.apache.activemq:activemq-all) 6.0.0 before 6.2.5 - Apache ActiveMQ (org.apache.activemq:apache-activemq) before 5.19.6 - Apache ActiveMQ (org.apache.activemq:apache-activemq) 6.0.0 before 6.2.5 Description: Improper Input Validation, Improper Control of Generation of Code ('Code Injection') vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ. An authenticated attacker may bypass the fix in CVE-2026-34197 by adding a connector using an HTTP Discovery transport via BrokerView.addNetworkConnector or BrokerView.addConnector through Jolokia if the activemq-http module is on the classpath. A malicious HTTP endpoint can return a VM transport through the HTTP URI which will bypass the validation added in CVE-2026-34197. The attacker can then use 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 5.19.6, from 6.0.0 before 6.2.5; Apache ActiveMQ All: before 5.19.6, from 6.0.0 before 6.2.5; Apache ActiveMQ: before 5.19.6, from 6.0.0 before 6.2.5. Users are recommended to upgrade to version 5.19.6 or 6.2.5, which fixes the issue.

An authenticated attacker can show malicious content when browsing queues in the web console by overriding the content type to be HTML (instead of XML) and by injecting HTML into a JMS selector field. This issue affects Apache ActiveMQ: before 5.19.6, from 6.0.0 before 6.2.5; Apache ActiveMQ Web: before 5.19.6, from 6.0.0 before 6.2.5. Users are recommended to upgrade to version 6.2.5 or 5.19.6, which fixes the issue.

An authenticated attacker can use the admin web console page to construct a malicious broker name that bypasses name validation to include an xbean binding that can be later used by a VM transport to load a remote Spring XML application. The attacker can then use the DestinationView mbean to send a message to trigger a VM transport creation that will reference this 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().
