  • Javascript Hijacking Brian Chess, Yekaterina Tsipenyuk O'neil, Jacob West
    JavaScript Hijacking Brian Chess, Yekaterina Tsipenyuk O'Neil, Jacob West March 12, 2007 Summary An increasing number of rich Web applications, often called AJAX applications, make use of JavaScript as a data transport mechanism. This paper describes a vulnerability we term JavaScript Hijacking, which allows an unauthorized party to read sensitive data contained in JavaScript messages. The attack works by using a <script> tag to circumvent the Same Origin Policy enforced by Web browsers. Traditional Web applications are not vulnerable because they do not use JavaScript as a data transport mechanism. We analyzed the 12 most popular AJAX frameworks, including 4 server-integrated toolkits – Direct Web Remoting (DWR), Microsoft ASP.NET AJAX (a.k.a. Atlas), XAJAX and Google Web Toolkit (GWT) -- and 8 purely client-side libraries -- Prototype, Script.aculo.us, Dojo, Moo.fx, jQuery, Yahoo! UI, Rico, and MochiKit. We determined that among them only DWR 2.0 implements mechanisms for preventing JavaScript Hijacking. The rest of the frameworks do not explicitly provide any protection and do not mention any security concerns in their documentation. Many programmers are not using any of these frameworks, but based on our findings with the frameworks, we believe that many custom-built applications are also vulnerable. An application may be vulnerable if it: • Uses JavaScript as a data transfer format • Handles sensitive data We advocate a two-pronged mitigation approach that allows applications to decline malicious requests and prevent attackers from directly executing JavaScript the applications generate. 1. Introduction1 Although the term “Web 2.0” does not have a rigorous definition, it is commonly used in at least two ways.

  • Mastering Ajax, Part 1: Introduction to Ajax Understanding Ajax, a Productive Approach to Building Web Sites, and How It Works
    Mastering Ajax, Part 1: Introduction to Ajax Understanding Ajax, a productive approach to building Web sites, and how it works Skill Level: Introductory Brett McLaughlin ([email protected]) Author and Editor O'Reilly Media Inc. 06 Dec 2005 Ajax, which consists of HTML, JavaScript™ technology, DHTML, and DOM, is an outstanding approach that helps you transform clunky Web interfaces into interactive Ajax applications. The author, an Ajax expert, demonstrates how these technologies work together -- from an overview to a detailed look -- to make extremely efficient Web development an easy reality. He also unveils the central concepts of Ajax, including the XMLHttpRequest object. Five years ago, if you didn't know XML, you were the ugly duckling whom nobody talked to. Eighteen months ago, Ruby came into the limelight and programmers who didn't know what was going on with Ruby weren't welcome at the water cooler. Today, if you want to get into the latest technology rage, Ajax is where it's at. However, Ajax is far more than just a fad; it's a powerful approach to building Web sites and it's not nearly as hard to learn as an entire new language. Before I dig into what Ajax is, though, let's spend just a few moments understanding what Ajax does. When you write an application today, you have two basic choices: • Desktop applications • Web applications These are both familiar; desktop applications usually come on a CD (or sometimes are downloaded from a Web site) and install completely on your computer.

  • The Web 2.0 Demystified – Six Theses on a Misinterpreted Concept
    Chapter 4 – Applications and Impacts The Web 2.0 Demystified – Six Theses on a Misinterpreted Concept H.D.Hofmann1 and M.H.Knahl2 1University of Cooperative Education, Mannheim, Germany 2Centre for Information Security and Network Research, University of Plymouth, United Kingdom e-mail: [email protected], [email protected] Abstract The Web 2.0 was said to bring real innovation, new concepts, and new applications to the Web. The role of a user is upgraded by changing his passive role of information consumer to the role of somebody producing and consuming information at the same time ("prosumer"). In our paper, we discuss the major aspects of the concept Web 2.0 and draw conclusions from our findings by means of theses. It is argued that technologies used with Web 2.0 do not represent an innovative factor. We discuss technical aspects such as technologies and programming interfaces as well as usability aspects and business aspects of Web 2.0 applications and give an outlook to future developments and new concepts used on the Web. Based on the derived theses it is proposed that the Web 3.0 will bring new concepts and applications to the web rather than the Web 2.0. Keywords Web 2.0, Web 3.0, Internet Applications, AJAX 1. Web 2.0 - old wine in new skins? The past 10-15 have seen a rapid development and adoption of Internet services. Business managers have been enthused but also alarmed by a rapidly proliferating series of developments to the internet and web based services that alter consumer behaviour and have the potential to transform business models (Cassidy, 2002; Tapscott and Williams, 2007).

  • Using Ajax with PHP and Sajax How the Simple Ajax Toolkit Can Integrate Your Server-Side PHP with Javascript
    Using Ajax with PHP and Sajax How the Simple Ajax Toolkit can integrate your server-side PHP with JavaScript Skill Level: Intermediate Tyler Anderson ([email protected]) Freelance Writer Stexar Corp. 18 Oct 2005 Updated 05 Jul 2006 For years, the goal of creating a truly responsive Web application was hampered by one simple fact of Web development: To change the information on part of a page, a user must reload the entire page. Not anymore. Thanks to asynchronous JavaScript and XML (Ajax), we can now request new content from the server and change just part of a page. This tutorial explains how to use Ajax with PHP and introduces the Simple Ajax Toolkit (Sajax), a tool written in PHP that lets you integrate server-side PHP with JavaScript that makes this work. Section 1. Before you start This tutorial is for those interested in developing rich Web applications that dynamically update content using asynchronous JavaScript and XML (Ajax) with PHP, without having to refresh entire Web pages with each user click. This tutorial assumes basic PHP concepts, including the use of if and switch statements, and functions. About this tutorial Using Ajax with PHP and Sajax © Copyright IBM Corporation 1994, 2008. All rights reserved. Page 1 of 25 developerWorks® ibm.com/developerWorks You will learn about Ajax, as well as issues surrounding its usage. You will also build an Ajax application in PHP that will display panels of a section of a previously written tutorial. Clicking on a panel link will reload only the content section and replace it with the content of the selected panel, saving bandwidth and time loading the page.

  • Il Framework XAJAX
    Il framework XAJAX Vincenzo Della Mea (PWLS 6.11, 6.12, 6.13) Complementi di Tecnologie Web – M. Franceschet, V.Della Mea e I.Scagnetto - 1 Sommario • XAJAX – Principi e API • Un esempio semplice: – rivisitazione del cambio di colori dello sfondo della pagina corrente. • Un esempio complesso: – generazione “interattiva” del codice fiscale Complementi di Tecnologie Web – M. Franceschet, V.Della Mea e I.Scagnetto - 2 XAJAX • http://xajaxproject.org/ • Framework in PHP per lo sviluppo di applicazioni AJAX: – generazione automatica delle funzioni Javascript che ruotano attorno a XmlHttpRequest; – codice PHP per l’accesso al DOM della pagina (tradotto ovviamente in Javascript); – non è richiesta nessuna conoscenza di Javascript. Complementi di Tecnologie Web – M. Franceschet, V.Della Mea e I.Scagnetto - 3 XAJAX: Oggetti principali • xajax_core: – xajax – xajaxRequest – xajaxResponse – xajaxControl – xajaxPlugin • xajax_js: – DOM, events, CSS, … • xajax_controls: validatori (X)HTML, … • xajax_plugins: GoogleMaps, HTML table Complementi di Tecnologie Web – M. Franceschet, V.Della Mea e I.Scagnetto - 4 Tipico pattern di utilizzo • Solitamente si creano tre file PHP: – un file di configurazione, – un file per la componente lato server, – un file per la componente lato client. • Il file di configurazione viene incluso ed utilizzato dagli altri due. Complementi di Tecnologie Web – M. Franceschet, V.Della Mea e I.Scagnetto - 5 XAJAX: cosa fare • Configurazione: – si include la libreria di classi xajax per mezzo del file xajax.inc.php; – si dichiara ed istanzia un oggetto xajax; – si registrano i nomi delle funzioni fornite dal server e chiamate asincronamente dal client. • Server: – si include la configurazione; – si definiscono le funzioni registrate in modo che ritornino valori o modifichino il DOM; – si elaborano le richieste con apposito metodo processRequest.

  • XAJAX: Una Librería De AJAX Para PHP (Parte 1)
    XAJAX: una librería de AJAX para PHP (parte 1) AJAX es el acrónimo de Asynchronous Javascript And XML o Javascript y XML asíncronos dicho en nuestro idioma. Se trata de una combinación de tecnologías que se ha popularizado muchísimo desde hace unos años con la irrupción de la Web 2.0 y lo podemos encontrar en infinidad de páginas y servicios web como Gmail, Google Maps, Hotmail, Flickr y un largo etcétera. La clave de AJAX está en que es asíncrono, es decir, permite que la página del cliente realice peticiones al servidor sin recargar la página. Sólo se actualizan las partes de la página que nos interesan pero sin tener que recargar la página entera, lo que proporciona una sensación de navegación mucho más fluida. Para introducirnos en el mundo de AJAX vamos a utilizar una librería llamada XAJAX que nos permite aprovechar las capacidades de AJAX en nuestras páginas PHP. Podéis descargar esta librería en la página del proyecto http://xajaxproject.org/ A continuación, unos de códigos de ejemplo que se presentarán en diferentes capítulos para que sean más fáciles de leer. También se puede descargar la versión PDF con todos los ejemplos aquí. Y un Zip con los códigos fuente. Ejemplo 1. Introducción a la librería. Comencemos con un simple ‘Hola, mundo’ para ir calentando. En esta ocasión lo ponemos todo en el mismo archivo PHP llamado ‘holaAjax.php’. ‘holaAjax.php’ <?php require ('xajax/xajax.inc.php'); $xajax = new xajax(); function cambia_texto($mensaje){ $respuesta = new xajaxResponse(); $respuesta->addAssign("mensaje","innerHTML",$mensaje); return $respuesta; } $xajax->registerFunction("cambia_texto"); $xajax->processRequests(); ?> <html> <head> <?php $xajax->printJavascript("xajax/"); ?> </head> <body> <input type="button" onclick="xajax_cambia_texto('Hola Ajax);" value="Pulsa" /> <div id="mensaje"></div> </body> </html> Explicación: Lo primero que debemos hacer es importar la librería de xajax y crear una instancia de xajax: require ('xajax/xajax.inc.php'); xajax = new xajax(); A continuación definimos las funciones que se van a utilizar.
