CVE-2015-2342 is a vulnerability in the JMX RMI service of VMware vCenter Server versions 5.0 before u3e, 5.1 before u3b, 5.5 before u3, and 6.0 before u1. The service does not restrict the registration of MBeans, allowing remote attackers to register malicious MBeans via the RMI protocol. This can lead to arbitrary code execution on the affected vCenter Server.

This repository contains a single Metasploit module (modules/exploits/multi/misc/java_jmx_server.rb) that exploits insecure configurations in Java JMX servers (CVE-2015-2342). The exploit targets JMX RMI interfaces that allow remote class loading via MLet, typically when authentication is disabled or misconfigured. The module acts as an HTTP server, serving a malicious MLet HTML and Java JAR payload containing MBeans. When the vulnerable JMX server loads the MLet, it fetches and executes the attacker's Java code, resulting in remote code execution. The exploit is weaponized, leveraging Metasploit's payload system to deliver arbitrary Java payloads. The main attack vector is network-based, targeting exposed JMX RMI endpoints. The module is well-structured, with clear separation of payload serving and exploitation logic, and is suitable for use in penetration testing scenarios where insecure JMX configurations are suspected.
