EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
Once an user is authenticated on Jolokia, he can potentially trigger arbitrary code execution.
In details, in ActiveMQ configurations, jetty allows org.jolokia.http.AgentServlet to handler request to /api/jolokia
org.jolokia.http.HttpRequestHandler#handlePostRequest is able to create JmxRequest through JSONObject. And calls to org.jolokia.http.HttpRequestHandler#executeRequest.
Into deeper calling stacks, org.jolokia.handler.ExecHandler#doHandleRequest is able to invoke through refection.
And then, RCE is able to be achieved via jdk.management.jfr.FlightRecorderMXBeanImpl which exists on Java version above 11.
1 Call newRecording.
2 Call setConfiguration. And a webshell data hides in it.
3 Call startRecording.
4 Call copyTo method. The webshell will be written to a .jsp file.
The mitigation is to restrict (by default) the actions authorized on Jolokia, or disable Jolokia. A more restrictive Jolokia configuration has been defined in default ActiveMQ distribution. We encourage users to upgrade to ActiveMQ distributions version including updated Jolokia configuration: 5.16.6, 5.17.4, 5.18.0, 6.0.0.
