SecurityTracker Alert ID:  1039837
SecurityTracker URL:  http://securitytracker.com/id/1039837
CVE Reference:   CVE-2017-4929   (Links to External Site)
Date:  Nov 17 2017
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): 6.2.x, 6.3.x
Description:   A vulnerability was reported in VMware NSX Edge. 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 VMware NSX Edge 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.

Jarad Kopf of Deltek and Issam Rabhi independently reported this vulnerability.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the VMware NSX 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:   VMware has issued a fix (NSX for vSphere 6.2.9, 6.3.5).
