DESCRIPTION:
A vulnerability has been discovered in SilverStripe, which can be
exploited by malicious people to conduct cross-site scripting
attacks.

Input appended to the URL via e.g. admin/reports/ is not properly
sanitised in the "process()" function in sapphire/core/SSViewer.php
before being returned to the user. This can be exploited to execute
arbitrary HTML and script code in a user's browser session in context
of an affected site.

Successful exploitation requires that the victim uses a browser that
does not URL-encode the request (e.g. Internet Explorer 6).

The vulnerability is confirmed in version 2.4.5. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
