Description: A vulnerability was reported in the Prestige 660H-61 Router. A remote user can conduct cross-site scripting attacks.
The router administration interface 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 Prestige Router device 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:
