Description:
A vulnerability was reported in the APC Switched Rack PDU. A remote user can conduct cross-site scripting attacks.
The web administration login page ('login1') does not properly filter HTML code from user-supplied input in the 'login_username' 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 APC device 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 vendor was notified on June 18, 2009.
A demonstration exploit URL is provided:
http://[target]/Forms/login1?login_username=<ScRiPt>alert('hello');</ScRiPt>
