CVE-2016-4117 is a vulnerability in Adobe Flash Player affecting version 21.0.0.226 and earlier. It allows a remote attacker to execute arbitrary code via crafted content delivered through Flash-based attack chains. The flaw was exploited in the wild in 2016, including in watering-hole, malvertising, and malicious-document campaigns. Observed intrusion activity shows the vulnerability being used as a client-side execution vector against users running vulnerable Flash versions, often through embedded Flash objects in Microsoft Office documents or through web-based exploit infrastructure. Specific details about the vulnerable function or root cause are not available from the provided information.

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.
