CVE-2010-0886 is an insufficient argument-validation vulnerability in the Java Deployment Toolkit plugin and ActiveX control included with Oracle Java SE and Java for Business JDK and JRE 6 Update 10 through 19. A crafted JNLP URL can trigger arbitrary code execution when processed through a specially crafted HTML document.

This repository contains a single Metasploit module: 'java_ws_arginject_altjvm.rb', which exploits a command line argument injection vulnerability in the Sun Java Web Start plugin (CVE-2010-0886, CVE-2010-1423) on Windows systems. The module acts as an HTTP server, serving malicious content to browser users with vulnerable Java Web Start plugins. By abusing the '-J' and '-XXaltjvm' options, the attacker can inject arbitrary arguments to the Java runtime, leading to remote code execution. The exploit requires the attacker to run the module as root on a server that does not serve SMB, and the target must have the WebClient (WebDAV Mini-Redirector) service enabled. The module supports customizable payloads (such as reverse shells) and is operational in nature. The main entry point is the Ruby file itself, which is structured as a standard Metasploit exploit module and leverages the Metasploit framework's HTTP server and EXE delivery capabilities. The only fingerprintable endpoints are the HTTP server (typically on port 80) and an optional UNC path for payload delivery.
