Gallery Input Validation Error in 'include' Variable Lets Remote Users Conduct Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1012064
SecurityTracker URL:  http://securitytracker.com/id/1012064
CVE Reference:   CVE-2004-1106   (Links to External Site)
Updated:  Dec 1 2004
Original Entry Date:  Nov 3 2004
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): prior to 1.4.4-pl3
Description:   An input validation vulnerability was reported in Gallery. A remote user can conduct cross-site scripting attacks.

The vendor reported that 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 Gallery 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 flaw resides in several files, including 'view_photo.php', 'index.php', and 'init.php'. In 'index.php', the 'include' variable is not properly escaped before being displayed.

The vendor credits Jim Paris with discovering this flaw.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Gallery 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 released a fixed version (1.4.4-pl4), available at:

http://sourceforge.net/project/showfiles.php?group_id=7130

The version 1.4.4-pl3 contains an error and should not be used.

Vendor URL:  gallery.menalto.com/index.php (Links to External Site)
Cause:   Input validation error
