Description:  
Cross site scripting describes attacks that allow to insert malicious  
html or javascript code via get or post forms. This can be used to steal  
session cookies.  
helma is a javascript-based application server, gobi is a cms  
based on helma. It's used on some popular pages, e. g. the ORF.  
The search-function can be used to inject javascript code.  
It will cause an information disclosure about the system path of helma  
if filled with invalid chars.  
  
Workaround/Fix:  
There's no vendor fix. All input strings in web applications should be  
escaped properly and error messages containing paths should be suppressed  
on live installations.  
Vendor has been contacted 2007-04-12 and hasn't answered yet.
