Loading vulnerability…
A remote code execution vulnerability in Microsoft Silverlight 5 and Microsoft Silverlight 5 Developer Runtime before version 5.1.20125.0. The flaw occurs because Silverlight does not properly validate pointers during HTML object rendering, leading to a double dereference condition. A remote attacker can trigger the issue by convincing a target to load a crafted Silverlight application, which can corrupt process memory and result in arbitrary code execution in the context of the affected application.

This repository contains a single Metasploit module targeting Microsoft Silverlight (CVE-2013-0074, CVE-2013-3896) via a browser-based attack. The exploit abuses unsafe memory access in the ScriptObject.Initialize() method, allowing arbitrary code execution when a victim visits a malicious web page. The module serves a crafted Silverlight XAP package and DLL, along with a XAML manifest, to the victim's browser. The payload is customizable and typically results in a reverse shell or Meterpreter session. The exploit is effective against Windows XP SP3 and Windows 7 SP1 running Internet Explorer 6-10 with Silverlight enabled. The repository is structured as a single Ruby file compatible with the Metasploit framework, leveraging its BrowserExploitServer mixin to deliver the exploit and payload files dynamically based on incoming HTTP requests.
