This repository contains a single Metasploit module: 'modules/exploits/multi/browser/java_jre17_jmxbean_2.rb'. The module exploits CVE-2013-0431, a remote code execution vulnerability in Oracle Java 7 (Update 10, 11, and possibly earlier 7.x versions) via the JMX classes in a Java applet. The exploit is delivered through a malicious HTTP server that serves a crafted HTML page and a JAR file containing the exploit payload. When a victim visits the attacker's web page with a vulnerable Java plugin enabled, arbitrary code can be executed on their system. The module supports multiple payloads, including Java and native payloads for Windows, Linux, and Mac OS X. The structure is typical for a Metasploit browser exploit: it includes HTTP server logic, payload generation, and dynamic HTML/JAR delivery. No hardcoded IPs or external domains are present; the main fingerprintable endpoints are the root path and dynamically generated JAR file paths served by the module.
