Description: JavaScript injection is a type of attack where malicious JavaScript code is injected into a web application. This type of vulnerability allows attackers to execute scripts in users’ browsers, which can result in the theft of sensitive information, manipulation of the user interface, or redirection to malicious sites. JavaScript injection is considered a form of Cross-Site Scripting (XSS) attack, which occurs when a web application does not properly validate user input or sanitize output. This type of attack can have serious consequences for web application security, as it can compromise data integrity and user privacy. JavaScript injection is relevant in the context of cyber intelligence, penetration testing, and web application security, as security professionals must be vigilant about these vulnerabilities to protect their systems. Additionally, vulnerability analysis tools and environments are used by security professionals to identify and exploit these weaknesses, while defenders work to protect against such attacks.
