The vulnerability is remotely exploitable through the RMI interface, and requires the presence of gadget\u2011chain libraries in the JVM classpath. The realistic likelihood of exploitation depends on whether the environment exposes the JMX/RMI port externally and whether vulnerable libraries are present.
