Vulnerability Scanning Web 2.0 Client-Side Components

Web 2.0 applications are a combination of several technologies such as Asynchronous JavaScript and XML (AJAX), Flash, JavaScript Object Notation (JSON), Simple Object Access Protocol (SOAP), Representational State Transfer (REST). All these technologies, along with cross-domain information access, contribute to the complexity of the application. We are seeing a shift towards empowerment of an end-user's browser by loading libraries.

All these changes mean new scanning challenges for tools and professionals. The key learning objectives of this article are to understand the following concepts and techniques:

* Scanning complexity and challenges in new generation Web applications
* Web 2.0 client-side scanning objectives and methodology
* Web 2.0 vulnerability detection (XSS in RSS feeds)
* Cross-domain injection with JSON
* Countermeasures and defense through browser-side filtering

Top 10 Ajax Security Holes and Driving Factors

One of the central ingredients of Web 2.0 applications is Ajax encompassed by JavaScripts. This phase of evolution has transformed the Web into a superplatform. Not surprisingly, this transformation has also given rise to a new breed of worms and viruses such as Yamanner, Samy and Spaceflash. Portals like Google, NetFlix, Yahoo and MySpace have witnessed new vulnerabilities in the last few months. These vulnerabilities can be leveraged by attackers to perform Phishing, Cross-site Scripting (XSS) and Cross-Site Request Forgery (XSRF) exploitation.
