- More information:
Several security vulnerabilities have been discovered in ActiveMQ, a Java message broker.
Apache ActiveMQ uses LocateRegistry.createRegistry() to create the JMX RMI registry and binds the server to the
jmxrmientry. It is possible to connect to the registry without authentication and call the rebind method to rebind jmxrmi to something else. If an attacker creates another server to proxy the original, and bound that, he effectively becomes a man in the middle and is able to intercept the credentials when an user connects.
The optional ActiveMQ LDAP login module can be configured to use anonymous access to the LDAP server.
The Java OpenWire protocol marshaller is vulnerable to Remote Code Execution. This vulnerability may allow a remote attacker with network access to either a Java-based OpenWire broker or client to run arbitrary shell commands by manipulating serialized class types in the OpenWire protocol to cause either the client or the broker (respectively) to instantiate any class on the classpath.
For Debian 10 buster, these problems have been fixed in version 5.15.16-0+deb10u1.
We recommend that you upgrade your activemq packages.
