Before jumping into the final post within our discussion on vulnerabilities in the MEAN stack, look back at the other four posts within this series discussing MongoDB, Express.js (Core), Express.js (Sessions and CSRF), and AngularJS. Development mode (Node.js/Express.js) By default, Express applications run in development mode unless the NODE_ENV environmental variable is set to another value. In development mode, Express […]

Before jumping into the latest post within our discussion on vulnerabilities in the MEAN stack, look back at the first three posts discussing MongoDB, ExpressJS (Core), and ExpressJS (Sessions and CSRF). AngularJS disabled SCE service Angular 1.2 and greater include the built-in Strict Contextual Escaping service ($sce) by default. This service strips malicious HTML tags (e.g., <script>, etc.), attributes (e.g., […]

Before diving into the latest post within our discussion on vulnerabilities in the MEAN stack, look back at the first two posts discussing MongoDB and ExpressJS (Part 1). Client-side session storage (ExpressJS) With MEAN stack applications, it is fairly common to store the session state client-side in either a JSON Web Token (JWT) or custom cookie object […]

Before jumping into the Express framework, get up to speed with Part 1 of this series which explores MongoDB. Stack precedence (ExpressJS) The Express framework allows developers to easily add multiple middleware plugins globally to all routes via app.use(). However, middleware order is important because it will only be applied to routes defined further down the […]

MEAN stack applications (MongoDB, Express.js, AngularJS, and Node.js) are becoming increasingly popular as lightweight, easily deployable frameworks due to a vast ecosystem of middleware plugins and dependencies. But just how secure are these technologies? Let’s examine some common vulnerabilities that are introduced either by using these components in their default configurations or due to common […]

Multiple versions of JBoss contain a vulnerability that can allow remote users to execute arbitrary code on the server running JBoss; mitigating this issue is not always as simple as upgrading JBoss to the latest version. The Java deserialization vulnerability (CVE 2015-7501 and CWE-502, disclosed in January 2015) affects specific classes within the Apache Commons-Collections […]
