Description:
A vulnerability was reported in the D-Link DSA-3100 Router. A remote user can conduct cross-site scripting attacks.
The 'login_error.shtml' script does not properly filter HTML code from user-supplied input in the 'uname' 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 D-Link Router interface and will run in the security context of that device. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the device, access data recently submitted by the target user via web form to the device, or take actions on the device acting as the target user.
A demonstration exploit URL is provided:
http://[target]/login_error.shtml?uname=%3CBODY%20ONLOAD=alert%28%27www.eazel.es%27%29%3E
