This repository contains a single Metasploit module targeting a type confusion vulnerability (CVE-2016-4117) in Adobe Flash Player on macOS systems. The exploit is delivered via a malicious web page, which serves a crafted SWF file to browsers (Safari or Firefox) running on macOS Sierra 10.12.3 with Flash Player version 21.0.0.182 or earlier. The module uses Metasploit's BrowserExploitServer to serve both the HTML and SWF payloads. The payload is customizable and delivered via the SWF, allowing for arbitrary code execution on the victim's machine. The code references a local SWF file (msf.swf) and embeds it in the HTML template, with the payload base64-encoded and passed as a FlashVar. The only external endpoint referenced is the standard Macromedia Flash ActiveX codebase URL. The module is operational and can be used to achieve code execution on vulnerable systems.
