Description: JavaScript file inclusion refers to a vulnerability that allows an attacker to inject and execute malicious JavaScript code within a web application. This technique relies on manipulating how an application loads and executes scripts, which can lead to unauthorized code execution. The consequences of this vulnerability can be devastating, as malicious code can steal sensitive information, redirect users to fraudulent sites, or even take control of the user’s session. JavaScript file inclusion can occur through various techniques, such as injecting scripts into forms, exploiting misconfigurations on the server, or failing to validate inputs. The dynamic nature of JavaScript and its ability to interact with a web page’s Document Object Model (DOM) make it an attractive target for attackers. Therefore, it is crucial for developers to implement appropriate security measures, such as input validation and the use of Content Security Policy (CSP), to mitigate the risk of malicious JavaScript file inclusion in their web applications.
