CVE-2015-3043 is a memory corruption vulnerability in Adobe Flash Player affecting versions before 13.0.0.281, 14.x through 17.x before 17.0.0.169 on Windows and OS X, and before 11.2.202.457 on Linux. Adobe’s description states that the flaw can be triggered via unspecified vectors and may allow an attacker to execute arbitrary code or cause a denial of service. The issue was exploited in the wild in April 2015. The provided context further indicates it was used by the Sednit/APT28/Fancy Bear group, including via the Sedkit exploit kit in targeted operations. Specific vulnerable functions or code paths are not provided in the supplied content.

This repository contains a single Metasploit module: 'adobe_flash_nellymoser_bof.rb', which exploits a buffer overflow vulnerability in Adobe Flash Player's handling of Nellymoser-encoded audio in FLV files (CVE-2015-3043 and CVE-2015-3113). The exploit targets both Windows and Linux platforms, specifically vulnerable versions of Flash Player running in Internet Explorer or Firefox browsers. The module sets up a browser exploit server that delivers a crafted HTML page, a malicious SWF, and a specially crafted FLV file to the victim. When the victim visits the exploit server with a vulnerable browser and Flash version, the exploit triggers a buffer overflow, allowing arbitrary code execution. The payload is fully customizable via Metasploit, making this a weaponized exploit. The only external endpoint referenced is the official Macromedia Flash ActiveX control CAB file, used for embedding Flash in the generated HTML. The repository is structured as a typical Metasploit module, with all exploit logic contained in a single Ruby file.
