RMI(Remote Method Invocation,远程方法调用)是从java1.1开始实现的,它大大增强了Java开发分布式应用的能力。RMI对接口有着强烈的依赖,在需要创建一个远程对象的时候,我们通过传递一个接口来隐藏基层的实施细节,所以客户得到远程对象的一个句柄时,它们真正得到的是接口句柄,然后本地代码通过接口操作远程对象。通过RM
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.ChainedTransformer;importorg.apache.commons.collections.functors.ConstantTransform...
RMI全称是Remote Method Invocation-远程方法调用,Java RMI在JDK1.1中实现的,其威力就体现在它强大的开发分布式网络应用的能力上,是纯Java的网络分布式应用系统的核心解决方案之一。其实它可以被看作是RPC的Java版本。但是传统RPC并不能很好地应用于分布式对象系统。而Java RMI 则支持存储于不同地址空间的程序级对象之间...

Java RMI(Java Remote Method Invocation)Java远程方法调用,是Java编程语言里一种用于实现远程过程调用的应用程序编程接口,使客户机上运行的程序可以调用远程服务器上的对象。远程方法调用特性使Java编程人员能够在网络环境中分布操作。RMI宗旨就是尽可能简化远程接口对象的使用。
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 the same remote object may execute concurrently...
(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, ...
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 "unmarsha...

Java Remote Method Invocation (RMI) allows you to write distributed objects using Java. This paper describes the benefits of RMI, and how you can connect it to existing and legacy systems as well as to components written in Java. RMI provides a simple and direct model for distributed computati...
