Quick assessment
Affected
Red Hat Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 7
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
EAP（Artemis）的默认反序列化配置允许反序列化。 使用 ，该类通过其 或 方法实现允许列表/阻止列表过滤机制。然而，默认情况下允许列表和阻止列表均为空。当允许列表为空（size == 0）时， 对所有类返回 true。这意味着默认情况下，所有类均可被反序列化。

Vulnerability Title
Artemis-server: artemis-jms-client: artemis-core-client: undertow-core: wildfly-messaging-activemq-subsystem: artemis messaging handlers in red hat eap permit deserialization by default
Source: CVE Program / CVE List V5
Vulnerability Description
EAP's Artemis deserialization configuration permits deserialization by default. ObjectMessage.getObject() uses ObjectInputStreamWithClassLoader, which implements allow-list/block-list filtering via its checkSecurity()/isTrustedType() method. However, by default both allow-list and block-list are empty. When the allow-list is empty (size == 0), isTrustedType() returns true for ALL classes. This means all classes are deserializable by default.
