Cross site scripting and information disclosure in gobi/helma
Cross site scripting describes attacks that allow to insert malicious
based on helma. It's used on some popular pages, e. g. the ORF.
It will cause an information disclosure about the system path of helma

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.
