Description:
A vulnerability was reported in Coppermine Photo Gallery. A remote user can conduct cross-site scripting attacks.
Several scripts do 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 Coppermine Photo 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 'referer' parameter in 'mode.php' is affected.
The 'log' parameter in the 'viewlog.php' scripts are affected.
A local user with administrative privileges can cause a local file to be included and executed on the target system with the privileges of the target web service. A demonstration exploit URL is provided:
http://localhost/cpg/viewlog.php?log=../../../../../../../../../etc/passwd%00
The vendor was notified on September 3, 2007.
