This repository contains a single Metasploit module targeting a pre-authentication remote code execution vulnerability in k5n.us WebCalendar version 1.2.4 and below (CVE-2012-1495). The exploit abuses the presence of an insecure installation script ('settings.php') to inject arbitrary PHP code, which is then triggered to execute attacker-supplied commands as the web server user. The module is written in Ruby and leverages the Metasploit framework's HTTP client capabilities. The attacker provides a base64-encoded command payload via an HTTP header, which is decoded and executed on the target. The module includes a check method to verify the target's version and is fully weaponized, allowing for customizable payloads. The main endpoints involved are the installation and settings scripts of the WebCalendar application.
