How to fix?

Upgrade org.apache.geode:geode-core to version 1.15.0 or higher.


org.apache.geode:geode-core is a data management platform for cloud architectures.

Affected versions of this package are vulnerable to Deserialization of Untrusted Data when using JMX over RMI on Java 8.

Note: Users should also upgrade to Java 11.

If upgrading to Java 11 is not possible, then upgrade to the fixed version and specify --J=-Dgeode.enableGlobalSerialFilter=true when starting any Locators or Servers.


Users who are not able to do any of the above steps should disable affected services such as JMX over RMI (unless they are required) by setting Geode property jmx-manager to false. This property defaults to false on Servers and true on Locators.


Serialization is a process of converting an object into a sequence of bytes which can be persisted to a disk or database or can be sent through streams. The reverse process of creating object from sequence of bytes is called deserialization. Serialization is commonly used for communication (sharing objects between multiple hosts) and persistence (store the object state in a file or a database). It is an integral part of popular protocols like Remote Method Invocation (RMI), Java Management Extension (JMX), Java Messaging System (JMS), Action Message Format (AMF), Java Server Faces (JSF) ViewState, etc.

Deserialization of untrusted data (CWE-502) is when the application deserializes untrusted data without sufficiently verifying that the resulting data will be valid, thus allowing the attacker to control the state or the flow of the execution.
