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.

Is your Apache ActiveMQ deployment affected?

If you're running <5.15.16; >=5.16.0 <5.16.7; >=5.17.0 <5.17.6; >=5.18.0 <5.18.3, you need this patch. Book a discovery call to get covered.
