Technical Description
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.
Users are recommended to upgrade
both brokers and clients to version 5.15.16, 5.16.7, 5.17.6, or 5.18.3
which fixes this issue.
Remediation
Check the references section for vendor advisories and patches from apache. Update activemq to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
