Severity: high - possible RCE

Description:

Apache Geode versions prior to 1.15.0 are vulnerable to a deserialization of untrusted data \
flaw when using REST API on Java 8 or Java 11.

Any user wishing to protect against deserialization attacks involving REST APIs should upgrade \
to Apache Geode 1.15 and follow the documentation for details on enabling \
"validate-serializable-objects=true" and specifying any user classes that may be \
serialized/deserialized with "serializable-object-filter". Enabling \
"validate-serializable-objects" may impact performance.

Mitigation:

Disable affected services such as JMX over RMI or REST APIs unless they are required. REST APIs \
can be disabled by setting `http-service-port` to zero.
