A FFOGATO : runtime detection of injection attacks for Node.js

Node.js took JavaScript from the browser to server-side web applications, and injection vulnerabilities are now commonly reported in Node.js modules. However, existing taint analysis approaches for JavaScript require extensive manual modelling, and fail to analyse simple Node.js applications that contain hundreds of third-party modules. For this reason, we developed A FFOGATO , a robust and practical grey-box taint analysis tool that uses black-box reasoning to overcome the need for manual modelling while using white-box program analysis to reason about critical program operations. We evaluate A FFOGATO on a suite of Node.js modules and show how it can detect all publicly disclosed injection vulnerabilities with an acceptable overhead, outperforming existing state-of-the-art tools for Node.js.
