Hi

Is there any way to prevent a XSS attacks in cold fusion in already established project?

I used encodeForHTML(url.NewValue) for an input but applying this to every input of Form of all the pages in the project won't be possible.

Is there a way to do this from single location without affecting rest of the code in project?

Which version of CF?

There are a number of settings in the CF Administrator that prevent XSS out of the box. Enable Global Script Protection under Server Settings > Settings is a good starting point.

Used it, but doesn't work for user input in a Form.

Thought of replacing CFSET with a Custom tag to provide some degree of protection. But variable name in custom tag does not support complex name using (.) operator. eg <cf_myset url.value="123">
