SecurityTracker Alert ID:  1031302
SecurityTracker URL:  http://securitytracker.com/id/1031302
CVE Reference:   CVE-2014-3797   (Links to External Site)
Date:  Dec 5 2014
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  
Version(s): vCSA 5.1
Description:   A vulnerability was reported in VMware vCenter Server Appliance (vCSA). A remote user can conduct cross-site scripting attacks.

The system does not properly filter HTML code from user-supplied input before displaying the input. A remote user can create a specially crafted URL that, when loaded by a target user, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the VMware vCenter Server Appliance (vCSA) interface 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.

Tanya Secker of Trustwave SpiderLabs reported this vulnerability.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the VMware vCenter Server Appliance (vCSA) interface, 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 (5.1 Update 3).
