CVE-2012-0500 is a critical remote code execution vulnerability in Oracle Java Web Start, affecting Java SE 7 Update 2 and earlier, Java SE 6 Update 30 and earlier, and JavaFX 2.0.2 and earlier. The vulnerability arises from improper input validation during the processing of execution parameters in Java Web Start, allowing remote unauthenticated attackers to execute arbitrary code on a victim's system by enticing them to open a malicious JNLP file. The flaw can be exploited via untrusted Java Web Start applications and applets, impacting confidentiality, integrity, and availability.

This repository contains a single Metasploit module (modules/exploits/windows/browser/java_ws_vmargs.rb) that exploits CVE-2012-0500, a command line argument injection vulnerability in the Sun Java Web Start plugin on Windows. The module acts as a malicious HTTP server, delivering a crafted JNLP file that abuses the '-J' and '-XXaltjvm' options to load a DLL payload from a UNC path. The exploit targets Windows systems with the WebClient (WebDAV Mini-Redirector) service enabled. When a vulnerable client accesses the malicious server, the exploit delivers a DLL payload (generated by Metasploit) that is executed on the target system, allowing arbitrary code execution. The module requires the server to be run as root, listening on port 80 with the root URI path. The structure is typical for a Metasploit exploit: it includes HTTP server logic, payload generation, and request handling for various HTTP/WebDAV methods. No hardcoded IPs or domains are present; endpoints are dynamically generated based on configuration and randomization.
