SecurityTracker Alert ID:  1025322
SecurityTracker URL:  http://securitytracker.com/id/1025322
CVE Reference:   CVE-2011-1168   (Links to External Site)
Date:  Apr 12 2011
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): 4.4.x, 4.5.x and 4.6.x; (KDE SC 4.4.0 through KDE SC 4.6.1)
Description:   A vulnerability was reported in KDE Konqueror. A remote user can conduct cross-site scripting attacks.

The error page 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 potentially run in the security context of an arbitrary 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 vendor was notified on March 16, 2011.
