Top 10 Web 2.0 Attack Vectors by Shreeraj Shah on 22/11/06

Web 2.0 is the novel term coined for new generation Web applications. start.com, Google maps, Writely and MySpace.com are a few examples. The shifting technological landscape is the driving force behind these Web 2.0 applications. On the one hand are Web services that are empowering server-side core technology components and on the other hand are AJAX and Rich Internet Application (RIA) clients that are enhancing client-end interfaces in the browser itself. XML is making a significant impact at both presentation and transport (HTTP/HTTPS) layers. To some extent XML is replacing HTML at the presentation layer while SOAP is becoming the XML-based transport mechanism of choice.

This technological transformation is bringing in new security concerns and attack vectors into existence. Yamanner, Samy and Spaceflash type worms are exploiting “client-side” AJAX frameworks, providing new avenues of attack and compromising some of the confidential information. On the “server-side”, XML based Web services are replacing some of the key functionalities and providing distributed application access through Web services interfaces. These remote capabilities to invoke methods over GET, POST or SOAP from the Web browser itself provide new openings to applications. On other side, RIA frameworks running on XML, XUL, Flash, Applets and JavaScripts are adding new possible sets of vectors. RIA, AJAX and Web services are adding new dimensions to Web application security.
