Description:   A vulnerability was reported in Microsoft SharePoint. A remote user can conduct cross-site scripting attacks. Microsoft Project Server is affected.

The software does not properly filter HTML code from user-supplied input before displaying the input. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Microsoft SharePoint software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

Ashar Javed of Hyundai AutoEver Europe GmbH reported these vulnerabilities.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Microsoft SharePoint software, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
