Microsoft » Lync : Security Vulnerabilities, CVEs, Published In 2012 (XSS)

Cross-site scripting (XSS) vulnerability in Microsoft InfoPath 2007 SP2 and SP3 and 2010 SP1, Communicator 2007 R2, Lync 2010 and 2010 Attendee, SharePoint Server 2007 SP2 and SP3 and 2010 SP1, Groove Server 2010 SP1, Windows SharePoint Services 3.0 SP2, SharePoint Foundation 2010 SP1, and Office Web Apps 2010 SP1 allows remote attackers to inject arbitrary web script or HTML via a crafted string, aka "HTML Sanitization Vulnerability."

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."
