Splunk Web Input Validation Flaws Let Remote Conduct Cross-Site Scripting and Open Redirect Attacks
SecurityTracker Alert ID:  1036489
SecurityTracker URL:  http://securitytracker.com/id/1036489
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Aug 2 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  
Version(s): prior to versions 5.0.16, 6.0.12, 6.1.11, 6.2.11, 6.3.6, 6.4.2
Description:   Two vulnerabilities were reported in Splunk. 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. Versions 6.2.x, 6.3.x, and 6.4.x are affected.

Splunk Web 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 Internet Explorer browser. The code will originate from the site running the Splunk 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.

Noriaki Iwasaki (Cyber Defense Institute, Inc.) 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 Splunk 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 (5.0.16, 6.0.12, 6.1.11, 6.2.11, 6.3.6, 6.4.2).
