Description:
Richard Maudsley has reported a vulnerability in FirstClass, allowing malicious people to conduct Cross Site Scripting attacks.
The problem is that input passed to the "TargetName" parameter in "/.Templates/Commands/Upload.shtml" isn't properly verified before it is returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of a vulnerable site.
Solution:
Filter malicious requests using a firewall or a proxy server.
