SecurityTracker Alert ID:  1019967
SecurityTracker URL:  http://securitytracker.com/id/1019967
CVE Reference:   CVE-2008-2103   (Links to External Site)
Updated:  May 9 2008
Original Entry Date:  May 6 2008
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  Exploit Included:  Yes  
Version(s): 2.17.2 and higher
Description:   A vulnerability was reported in Bugzilla. A remote user can conduct cross-site scripting attacks.

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 Bugzilla 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 "Format for Printing" view of a bug and the "Long Format" of a bug list display modes are affected.

Bradley Baetz 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 Bugzilla 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 fixed versions (2.20.6, 2.22.4, 3.0.4, and 3.1.4), available at:
