Description: A vulnerability was reported in IBM WebSphere Application Server. A remote user can conduct cross-site scripting attacks.
The server's Internal Server Error page does not properly filter HTML code from user-supplied input before displaying the input via
the 'faultactor' tag. 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 IBM WebSphere 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.
A demonstration exploit request is provided:
GET /<SCRIPT>alert('Can%20Cross%20Site%20Attack')</SCRIPT>
HTTP/1.1
Host: 192.168.1.195:8880
Connection: close
