Draft Clearclick: Effective Client-Side Protection Against UI
Draft ClearClick: Effective Client-Side Protection Against UI Redressing Attacks Giorgio Maone <giorgio at maone.net> Rev. 2, May 3, 2012 Abstract “User Interface Redressing”, popularized in 2008 as “Clickjacking”, designates a class of attacks, leveraging ambient authority and the coexistence in modern user agents of multiple browsing contexts, which trick an authorized human into interacting with UI elements that actually belong to the targeted web application, but have been obscured or decontextualized by attacker-provided content. This interaction induces unintended application state changes on behalf of the victim – similarly to Cross Site Request Forgery – but defeats traditional CSRF protections, such as form tokens, by exploiting the legitimate web application UI itself, which those countermeasures are meant to validate. The main defense currently adopted by mainstream browsers requires a server- side opt-in signal and prohibits legitimate, widespread use cases such as cross-site subdocument embedding. Another countermeasure immune to these limitations (enabled by default, entirely client-side and designed to allow cross-domain embedding) is the ClearClick module, included in the NoScript add-on for Mozilla Firefox just days after the first Clickjacking announcement. This document describes the rationale behind it and the way it works. Keywords: clickjacking, anti-clickjacking, UI redressing, ClearClick, X-Frame-Options. 1. Introduction In September 2008, Jeremiah Grossman and Robert “RSnake” Hansen canceled a previously announced -
