This vulnerability allows a remote attacker with network access to a Java Management Extensions (JMX) or Remote Method Invocation (RMI) port on an instrumented Java Virtual Machine (JVM) running Java Development Kit (JDK) version 16 or earlier to achieve arbitrary remote code execution. This is possible because the RMI instrumentation registers a custom endpoint that deserializes incoming data without proper serialization filters, provided a compatible gadget-chain library is present on the classpath. Successful exploitation grants the attacker the same privileges as the user running the affected JVM.",
