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, patches, and mitigation guidance. 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.
