Someone says that my PHP code is vulnerable to XSS. I asked them what I should do to fix it, but now they don't want to help.
Here is the code:
$action=$_REQUEST['action'];
/* send the submitted data */
{
$name=$_REQUEST['name'];
$email=$_REQUEST['email'];
$message=$_REQUEST['message'];
if (($name=="")||($email=="")||($message==""))
{
echo "All fields are required, please fill <a href=\"\">the form</a> again.";
}
else{
$from="From: $name<$email>\r\nReturn-path: $email";
$subject="Message sent using your contact form";
mail("[email protected]", $subject, $message, $from);
echo "Email sent!";
}
}
?>
