Comment Re:Sanitizing user imput is the most important par (Score 2, Informative) 157

Although sanitizing user input gets the job done, what one should be doing is sanitizing the output .

An XSS attack exists because you are dynamically generating a web page with content you didn't intend: which contains executable script instead of where you intended dumb text (that you got from a database or that was entered earlier on by a (another) user). Sanitizing user input (which is the only factor you don't control) will help but if I enter <script>1+1</script> as some comment on for example a JavaScript forum, I would expect it to appear like that !

The definite solution to getting rid of XSS attacks is to use a modern toolkit that actively prevents this without ANY effort from the programmer. Like Wt for example does.
