encodeForHtml() vs htmlEditFormat()

encodeForHtml() (new in CF10) vs htmlEditFormat(), how are they different?

Solution

  • I think it is same as encodeForHTML function in java's OWASP ESAPI. More secure to avoid XSS attack to use content in HTML.

    <cfsavecontent variable="htmlcontent">
<html>
    <head>
        <script>function hello() {alert('hello')}</script>
    </head>
    <body>
        <a href="#bookmark">Book Mark &amp; Anchor</a><br/>
        <div class="xyz">Div contains & here.</div>
        <IMG     SRC=&#x6A&#x61&#x76&#x61&#x73&#x63&#x72&#x69&#x70&#x74&#x3A&#x61&#x6C&#x65&#x72&#x74&#x28&#    x27&#x58&#x53&#x53&#x27&#x29>
    <IMG SRC=&#0000106&#0000097&#0000118&#0000097&#0000115&#0000099&#0000114&#0000105&#0000112&#0000116&#0000058&#0000097&#0000108&#0000101&#0000114&#0000116&#0000040&#0000039&#0000088&#0000083&#0000083&#0000039&#0000041>
</body>
</html></cfsavecontent>
