Apache: >> Activemq >> 6.1.0 Security Vulnerabilities
Memory Allocation with Excessive Size Value vulnerability in Apache ActiveMQ.
During unmarshalling of OpenWire commands the size value of buffers was not properly validated which could lead to excessive memory allocation and be exploited to cause a denial of service (DoS) by depleting process memory, thereby affecting applications and services that rely on the availability of the ActiveMQ broker when not using mutual TLS connections.
This issue affects Apache ActiveMQ: from 6.0.0 before 6.1.6, from 5.18.0 before 5.18.7, from 5.17.0 before 5.17.7, before 5.16.8. ActiveMQ 5.19.0 is not affected.
Users are recommended to upgrade to version 6.1.6+, 5.19.0+, 5.18.7+, 5.17.7, or 5.16.8 or which fixes the issue.
Existing users may implement mutual TLS to mitigate the risk on affected brokers.

In Apache ActiveMQ 6.x, the default configuration doesn't secure the API web context (where the Jolokia JMX REST API and the Message REST API are located).
It means that anyone can use these layers without any required authentication. Potentially, anyone can interact with the broker (using Jolokia JMX REST API) and/or produce/consume messages or purge/delete destinations (using the Message REST API).
To mitigate, users can update the default conf/jetty.xml configuration file to add authentication requirement:
<bean id="securityConstraintMapping" class="org.eclipse.jetty.security.ConstraintMapping">
<property name="constraint" ref="securityConstraint" />
<property name="pathSpec" value="/" />
</bean>
Or we encourage users to upgrade to Apache ActiveMQ 6.1.2 where the default configuration has been updated with authentication by default.
