CVE-2010-0094 is a critical privilege escalation vulnerability in Oracle Java SE and Java for Business (6 Update 18 and 5.0 Update 23), specifically in the Java Runtime Environment's javax.management.remote.rmi.RMIConnectionImpl class. The vulnerability arises from deserialization of user-supplied data within a doPrivileged block, allowing untrusted code (such as Java Applets or Java Web Start applications) to execute with the full privileges of the user running the browser. Exploitation is possible by crafting a Serializable subclass of ClassLoader and delivering it via a MarshalledObject, bypassing the Java security sandbox. The vulnerability was addressed in Java 6 update 19 by moving deserialization outside the privileged block.

This repository contains a single Metasploit module (modules/exploits/multi/browser/java_rmi_connection_impl.rb) that exploits CVE-2010-0094, a deserialization vulnerability in Oracle's Java Runtime Environment (JRE) versions 6 (prior to update 19) and 5 (prior to update 23). The exploit works by serving a malicious HTML page with an embedded Java applet (Exploit.jar) to a victim's browser. When loaded, the applet leverages the deserialization flaw to execute arbitrary Java code, as defined by the attacker's chosen payload. The module dynamically generates and serves the malicious JAR file, which contains several Java class files and a serialized payload. The attack vector is browser-based, requiring the victim to visit the attacker's HTTP server with a vulnerable Java plugin enabled. The exploit is operational and allows for arbitrary code execution on the target system. The repository is structured as a typical Metasploit module, written in Ruby, and leverages Metasploit's HTTP server and payload generation capabilities.
