Find and Fix JavaScript Vulnerabilities Early in the SDLC

JavaScript is the programming language used to program the behavior of webpages, including creating interactive features like menus, forms, animations, and just about anything else that can improve your visitor’s experience of the webpage. Because of this ability to create highly responsive interfaces to provide dynamic functionality and improve the user experience, JavaScript is now used by approximately 93% of all websites in some way or another.

When your web browser renders JavaScript code, it is called a client side script. JavaScript can also be run on a web server to generate HTML documents, thus running a server-side script. All browsers have JavaScript engines that run JavaScript of webpages.

While JavaScript is extremely popular and useful to enhance the web applications, it is important to recognize that like any other language, JavaScript applications also come with their share of vulnerabilities. Over the years, JavaScript has been responsible for several security vulnerabilities. The most common JavaScript vulnerabilities are Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF).

It is extremely important to integrate secure coding practices into your software development lifecycle irrespective of what coding language you use. With the right vulnerability assessment measures in place, organizations can be sure that their developers are creating secure code, finding vulnerabilities as code is being written, and fixing any detected vulnerabilities as soon as they are found.

WhiteHat Sentinel Source now supports static analysis of client-side JavaScript (.js) files, based on the script source structure in the .html files. Most commonly used frameworks and dependency management systems are supported.
