Description:   Several vulnerabilities were reported in Microsoft SharePoint. A remote user can cause arbitrary code to be executed on the target user's system. A remote user can conduct cross-site scripting attacks.

A remote user can create a specially crafted file that, when loaded by the target user with Office, will execute arbitrary code on the target system [CVE-2016-0022, CVE-2016-0052, CVE-2016-0053].

The software does not properly filter HTML code from user-supplied input before displaying the input [CVE-2016-0039]. 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.


Impact:   A remote user can create content that, when loaded by the target user, will execute arbitrary code on the target user's system.

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.

Solution:   The vendor has issued a fix.
