use of string in place of URL (in anti XSS)

Question

use of string in place of URL (in anti XSS)

1.1k views Asked by Mayank Parnami At 14 September 2024 at 05:24

I need to find a way to implement encoding.

Since HTML Encoding is not working, hence I am using:

using System.Web.Security.AntiXss;

and then:

AntiXssEncoder.UrlEncode(**Iam passing string here**)

This measure resolves my issue(Positive results in HP Fortify), however I am concerned since instead of URL I am using string. Would this result into any impediments?

using System.Web.Security.AntiXss;

and then:

string Comment= AntiXssEncoder.XmlAttributeEncode(passing string here);

or to accept HTML tags that put text in bold or italics; check content manually.

    public static bool DangerousContent (string text)
    {
        bool Status = false;
        if (
            text.Contains("<body>") ||
            text.Contains("<embed>") ||
            text.Contains("<frame>") ||
            text.Contains("<script>") ||
            text.Contains("<frameset>") ||
            text.Contains("<html>") ||
            text.Contains("<iframe>") ||
            text.Contains("<style>") ||
            text.Contains("<layer>") ||
            text.Contains("<link>") ||
            text.Contains("<ilayer>") ||
            text.Contains("<meta>") ||
            text.Contains("<meta>") ||
            text.Contains("<applet>")
           )//can add more
        {
            Status = true; 
        }
        return Status;
    }
