CVE-2022-41678 Information

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.HttpRequestHandlerhandlePostRequest is able to create JmxRequest through JSONObject. And calls to org.jolokia.http.HttpRequestHandlerexecuteRequest.

Into deeper calling stacks org.jolokia.handler.ExecHandlerdoHandleRequest 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.
