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.

Summary dbcve.org

This is a deserialization vulnerability in the Java OpenWire protocol marshaller where an attacker can manipulate serialized class types to force the client or broker to instantiate arbitrary classes on the classpath, enabling remote code execution with shell command execution.

Mitigation

Upgrade affected brokers and clients to version 5.15.16, 5.16.7, 5.17.6, or 5.18.3. Until patched, restrict network access to OpenWire ports and disable the protocol if not required.
