Palo Alto PAN-OS Input Validation Flaw in GlobalProtect External Interface Lets Remote Users Conduct Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1038975
SecurityTracker URL:  http://securitytracker.com/id/1038975
CVE Reference:   CVE-2017-9467   (Links to External Site)
Date:  Jul 21 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  

Description:   A vulnerability was reported in Palo Alto PAN-OS. A remote user can conduct cross-site scripting attacks.

The GlobalProtect external interface 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 Palo Alto PAN-OS GlobalProtect external 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.

Systems with GlobalProtect configured are affected.

Jarrod Phelps from Uber reported this vulnerability.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the Palo Alto PAN-OS GlobalProtect external interface, access data recently submitted by the target user via web form to the interface, or take actions on the interface acting as the target user.
Solution:   The vendor has issued a fix (6.1.18, 7.0.16, 7.1.11, 8.0.3).
