## Weblogic远程代码执行(CVE-2024-20931)
Oracle WebLogic Server是一个用于构建、部署和管理企业级Java应用程序。AQjmsInitialContextFactory 是一个允许应用程序使用JNDI查找方式访问Oracle AQ提供消息服务的工厂类。ForeignOpaqueReference是一个对象，lookup时会调用getReferent函数，进行远程对象查询。 该漏洞是 CVE-2023-21839 漏洞绕过，在AQjmsInitialContextFactory初始化时会通过 JNDI获取远程的 DataSource，当通过反射修改 ForeignOpaqueReference 的 jndiEnvironment 和 remoteJNDIName 属性后，再次远程查询ForeignOpaqueReference对象会导致 JNDI 注入，从而直接接管 Oracle WebLogic Server 来执行未经授权的操作或访问系统敏感信息。
