SecurityTracker Alert ID:  1022910
SecurityTracker URL:  http://securitytracker.com/id/1022910
CVE Reference:   CVE-2009-4662   (Links to External Site)
Updated:  Mar 7 2010
Original Entry Date:  Sep 18 2009
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): 7.0 - 7.03 HP3, 8.0 - 8.0.0 HP2
Description:   A vulnerability was reported in Novell GroupWise WebAccess. A remote user can conduct cross-site scripting attacks.

The system does not properly filter HTML code from user-supplied input in the 'User.Theme.index' parameter 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 GroupWise 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.

Matt Foster of Netcraft, Ltd. reported this vulnerability.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the GroupWise 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 (7.03 Hot Patch 4 (HP4), 8.0 Support Pack 1 (SP1)).

The vendor's advisory is available at:
