Quick assessment

Affected

Red Hat Red Hat JBoss Enterprise Application Platform 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.

WildFly 的 IIOP 监听器可能在执行身份验证之前允许对输入流进行反序列化。如果攻击者能够访问 IIOP 端口，且目标 EJB 允许使用未指定类型的方法参数，同时运行类路径中存在可利用的 gadget 链，则攻击者可能构造并发送恶意对象，从而触发反序列化漏洞。
