>                 Key: ISIS-2373
>                 URL: https://issues.apache.org/jira/browse/ISIS-2373
>             Project: Isis
>          Issue Type: Bug
>          Components: Isis Viewer Wicket
>    Affects Versions: 1.17.0
>            Reporter: Stefan Wegener
>            Priority: Critical
>             Fix For: 2.0.0
>
>         Attachments: isis-xss-1.png, isis-xss-2.png
>
>
> First of all: I am not sure if the topic is placed here correctly as it might only affect the wicket-Dependency that isis is using. But: As the current wicket-version (7.9.0) that is used by isis is vulnerable to it, I should be relevant to you.
>  
> I created the following HTML-document named xss_box.html:
> {code:java}
> <html>
> <script language="JavaScript"> 
>     window.alert("Sometext");
> </script>
> <head>
>     <meta http-equiv="Content-Type" content="text/html;charset=utf-8">
> </head>
> <body>...</body>
> </html>
> {code}
> When selecting this document for an upload, usually a preview of the content will be shown. In this case the client uploading the file executes the javascript code and gets a modified preview content, as you can see in my attached images.
>  
> I do not know if later wicket-versions (currently the newest version is 7.16.0) are protected against this threat.
