Security of Web Browser Scripting Languages: Vulnerabilities, Attacks, and Remedies

چکیده
While conducting a security analysis of JavaScript and VBScript, the most popular scripting languages on the Web, we found some serious aws. Motivated by this outcome, we propose steps towards a sound de nition and design of a security framework for scripting languages on the Web. We show that if such a security framework had been integrated into the respective scripting languages from the very beginning, the probability of preventing the multiple security aws, that we and other research groups identi ed, would have been greatly increased.

متن کاملMay I? - Content Security Policy Endorsement for Browser Extensions
Cross-site scripting (XSS) vulnerabilities are among the most prevailing problems on the web. Among the practically deployed countermeasures is a``defense-in-depth'' Content Security Policy (CSP) to mitigate the effects of XSS attacks. However, the adoption of CSP has been frustratingly slow. This paper focuses on a particular roadblock for wider adoption of CSP: its interplay with browser exte...
متن کاملDocument Structure Integrity: A Robust Basis for Cross-site Scripting Defense
Cross-site scripting (or XSS) has been the most dominant class of web vulnerabilities in 2007. The main underlying reason for XSS vulnerabilities is that web markup and client-side languages do not provide principled mechanisms to ensure secure, ground-up isolation of user-generated data in web application code. In this paper, we develop a new approach that combines randomization of web applica...
