Descriptions
The Web Proxy Auto-Discovery (WPAD) functionality in Microsoft .NET Framework 2.0 SP2, 3.5, 3.5.1, 4, and 4.5 does not validate configuration data that is returned during acquisition of proxy settings, which allows remote attackers to execute arbitrary JavaScript code by providing crafted data during execution of (1) an XAML browser application (aka XBAP) or (2) a .NET Framework application, aka "Web Proxy Auto-Discovery Vulnerability."
La funcionalidad Web Proxy Auto-Discovery (WPAD) de Microsoft .NET Framework v2.0 SP2, v3.5, v3.5.1, v4 y v4.5 no valida los datos de configuración que se devuelven durante la adquisición de la configuración del proxy, lo que permite a atacantes remotos ejecutar código JavaScript proporcionando datos modificados durante la ejecución de (1) una aplicación de explorador XAML (tambien conocido como XBAP) o (2) una aplicación .NET Framework. Se trata de un problema también conocido como "Web Proxy Auto-Discovery vulnerabilidad".
