Subject: BrowserCRM vulnerable for XSS

Inputs in the BrowserCRM is not properly sanitized, and XSS is possible in a lot of the systems input fields and url parameters.

Some fields have been filtered in a basic form, so that simple scripting like "<script>alert('XSS')</script>" is not possible. Howevere, since the filtering is not based on white listing you can conduct successful XSS attacks with code like "<IMG SRC=javascript:alert(String.fromCharCode(88,83,83))>".
