+Deserialization vulnerability on Jolokia that allows authenticated users to perform Remote Code Execution (CVE-2022-41678)
+PRODUCT AFFECTED:
+This issue affects Apache ActiveMQ.
+
+PROBLEM:
+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.
+
+This issue is being tracked as AMQ-9201
+
+WORKAROUND:
+
+Upgrade to Apache ActiveMQ 5.16.6, 5.17.4, 5.18.0, 6.0.0.
