SecurityTracker Alert ID:  1029463
SecurityTracker URL:  http://securitytracker.com/id/1029463
CVE Reference:   CVE-2013-5042   (Links to External Site)
Date:  Dec 10 2013
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes

Description:   A vulnerability was reported in ASP.NET. A remote user can conduct cross-site scripting attacks.

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 ASP.NET 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.

Microsoft Visual Studio Team Foundation Server 2013 is also affected.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the ASP.NET 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.
