SharePoint Security Advisory Issued by Microsoft -- Visual Studio Magazine

Microsoft issued a security advisory on Thursday for a vulnerability in Microsoft Windows SharePoint Services 3.0 and Microsoft Office SharePoint Server 2007.

The vulnerability affecting those applications has elevation-of-privilege implications for organizations. An attacker can use a cross-site scripting (XSS) technique to "run arbitrary script" that may lead to the attacker gaining access rights on a Web site running SharePoint, according to the advisory.
