Loading vulnerability…
A stack-based buffer overflow exists in the PlayFileName property of the ActiveX control implemented in MediaDBPlayback.DLL version 2.2.0.5, part of the Moxa ActiveX SDK. Remote attackers can exploit this vulnerability by supplying an overly long value to the PlayFileName property, leading to execution of arbitrary code in the context of the user running the vulnerable control.

This repository contains a single Metasploit module targeting a stack buffer overflow vulnerability in the MOXA MediaDBPlayback ActiveX Control (MediaDBPlayback.DLL version 2.2.0.5). The exploit generates a malicious HTML file (default: msf.html) that, when opened in Internet Explorer 6 or 7 on Windows XP or Vista with the vulnerable ActiveX control installed, triggers a buffer overflow via the PlayFileName property. This allows arbitrary code execution using shellcode provided by the Metasploit payload system, encoded into JavaScript within the HTML. The module is operational and requires the victim to open the crafted HTML file in a vulnerable environment. The main fingerprintable elements are the generated HTML file, the specific ActiveX CLSID (5B32067A-121B-49DE-8182-91EB13DDF8D6), and the reference to the MOXA vendor site. The exploit is not a detection script or a fake, and is a typical file-format/browser-based attack delivered via a malicious file.
