OWASP AppSecUSA 2011: Next Generation Web Attacks -- HTML 5, DOM(L3) and XHR(L2)
Speaker: Shreeraj Shah
Browsers are escalating their feature set to accommodate new specifications like HTML 5, XHR Level 2 and DOM Level 3. It is forming the backbone of next generation applications running on mobile, PDA devices or desktops. The blend of DOM (Remote Execution stack) , XHR L2 (Sockets for injections) and HTML5 (Exploit delivery platform) is becoming an easy victim for attackers and worms. We have already witnessed these types of attacks on popular sites like Twitter, Facebook and Yahoo. It is of the essence to understand attack surface and vectors to protect next generation applications. We have an enormous expansion of attack surface after inclusion of features like audio/video tags, drag/drop APIs, CSS-Opacity, localstorage, web workers, DOM selectors, Mouse gesturing, native JSON, Cross Site access controls, offline browsing, etc. This extension of attack surface and exposure of server side APIs allow attacker to perform following lethal attacks and abuses.
XHR abuse with attacking Cross Site access controls using level 2 calls
JSON manipulations and poisoning
DOM API injections and script executions
Abusing HTML5 tag structure and attributes
Localstorage manipulation and foreign site access
Attacking client side sandbox architectures
DOM scrubbing and logical abuse
Browser hijacking and exploitation through advanced DOM features
One-way CSRF and abusing vulnerable sites
DOM event injections and controlling (Clickjacking)
Hacking widgets, mashups and social networking sites
Abusing client side Web 2.0 and RIA libraries
We will be covering the above attacks and their variants in detail along with some real life cases and demonstrations. It is also important to understand methods of discovering these types of vulnerabilities across the application base. We will see some new scanning tools and approaches to identify some of these key issues.
