其中创建了rmi的客户端,再基于动态代理来生成的cc链LazyMap,最后再传入构造好的Remote对象,触发对服务器端的攻击RCE。 packagecom.anbai.sec.rmi;importorg.apache.commons.collections.Transformer;importorg.apache.commons.collections.functors.C
RMI目前使用Java远程消息交换协议JRMP(Java Remote Messaging Protocol)进行通信。由于JRMP是专为Java对象制定的,Java RMI具有Java的"Write Once,Run Anywhere"的优点,是分布式应用系统的百分之百纯Java解决方案。用Java RMI开发的应用系统可以部署在任何支持JRE(Java Run Environment Java,运行环境)的平台上。但由于JRMP...

3.3.6 Remote Method Invocation Remote Method Invocation (RMI) is the object-oriented equivalent of RPC. Instead of remotely calling a procedure, a remote method is invoked. RMI was first introduced in the Java language, and this specific implementation is sometimes referred to as Java RMI. Howev...
Remote Method Invocation (RMI) The most fundamental means of inter-object communication in Java is method invocation. Mechanisms like the Java event model are built on simple method invocations between objects in the same virtual machine. Therefore, when we want to communicate between virtual ...
Remote Method Invocation (RMI) and Distributed Observers in JavaThe Proxy Pattern
(真正被 export 的 Proxy 对象持有的是 UnicastRef 对象),在 RMI Registry 端保存的是 Proxy 对象,RMI Client 通过 RMI Registry lookup 获取到 Proxy 对象,在 RMI Client 端对 RemoteObject 的操作,最终都通过 RemoteObjectInvocationHandler 委托给 UnicastRef#public Object invoke(Object proxy, Method method, ...
java.rmi.ServerExceptionThis exception is thrown as a result of a remote method invocation when a RemoteException is thrown while processing the invocation on the server, either while unmarshalling the arguments or executing the remote method itself. For examples, see Section A.3.1, "Possible ...
3.2 Thread Usage in Remote Method Invocations A method dispatched by the RMI runtime to a remote object implementation may or may not execute in a separate thread. The RMI runtime makes no guarantees with respect to mapping remote object invocations to threads. Since remote method invocation on...
RMI 指的是远程方法调用 (Remote Method Invocation)。它是一种机制,能够让在某个Java 虚拟机上的对象调用另一个Java 虚拟机中的对象上的方法。可以用此方法调用的任何对象必须实现Remote该远程接口。调用这样一个对象时,其参数为"marshalled" 并将其从本地虚拟机发送到远程虚拟机(该远程虚拟机的参数为 "...
