Descriptions
The toStaticHTML API (aka the SafeHTML component) in Microsoft Internet Explorer 8 and 9, Communicator 2007 R2, and Lync 2010 and 2010 Attendee does not properly handle event attributes and script, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted HTML document, aka "HTML Sanitization Vulnerability."
La API toStaticHTML (también conocido como componente SafeHTML) en Microsoft Internet Explorer v8 y v9, Communicator 2007 R2, y Lync 2010 y 2010 Attendee no maneja de forma correcta atributos de eventos y secuencias de comandos, lo que facilita a atacantes remotos conducir ataques de ejecución de secuencias de comandos en sitios cruzados (XSS) a través de un documento HTML manipulado, también conocido como "HTML Sanitization Vulnerability."
The *toStaticHTML* component, which is found in Internet Explorer versions greater than 8, SharePoint and Lync is used to sanitize HTML fragments from dynamic and potentially malicious content. An attacker is able to create a specially formed CSS that will overcome * toStaticHTML*'s security logic; therefore, after passing the specially crafted CSS string through the *toStaticHTML* function, it will contain an expression that triggers a JavaScript call.
