Description: Remote code execution of JavaScript is a critical vulnerability that allows an attacker to execute arbitrary JavaScript code on a victim’s machine. This can occur through various techniques, such as injecting scripts into web applications, where malicious code runs in the user’s browser context. This vulnerability is particularly dangerous because it can be used to steal sensitive information, such as login credentials, or to perform unauthorized actions on behalf of the user. Remote execution of JavaScript code can be facilitated by flaws in input validation, incorrect security configurations, or lack of patches in software. The nature of JavaScript, which runs on the client side, makes it an attractive vector for attackers, as it can directly interact with the Document Object Model (DOM) of the web page and manipulate its content. Furthermore, many browsers allow the execution of third-party scripts, which amplifies the risk that an attacker could inject malicious code that runs without the user’s knowledge. Therefore, protection against this vulnerability is essential to maintain the security of web applications and user privacy.
