Fortinet FortiGate/FortiOS Input Validation Flaws Let Remote Users Conduct Open Redirect and Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1035332
SecurityTracker URL:  http://securitytracker.com/id/1035332
CVE Reference:   CVE-2016-3978   (Links to External Site)
Updated:  Apr 12 2016
Original Entry Date:  Mar 21 2016
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of system information, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  Exploit Included:  Yes  
Version(s): 5.0.x, 5.2.x, 5.4.x
Description:   A vulnerability was reported in Fortinet FortiGate/FortiOS. A remote user can redirect the target user's browser to an arbitrary site. A remote user can conduct cross-site scripting attacks.

A remote user can create a URL that, when loaded by the target user, will redirect the target user's browser to an arbitrary site.

A demonstration exploit URL is provided:

http[s]://[target]/login?redir=http[:]//[redirect site]

The software 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 site running the Fortinet FortiGate/FortiOS 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.

The 'redir' parameter is affected.

A demonstration exploit URL is provided:

http[s]://[target]/login?redir=javascript:alert(document.cookie)

Javier Nieto from www.behindthefirewalls.com reported these vulnerabilities.

Impact:   A remote user can cause the target user's browser to be redirected to an arbitrary web site.

A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Fortinet FortiGate/FortiOS 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 (5.0.13, 5.2.3, 5.4.0).

The vendor's advisory is available at:
