During an HTTP Response Splitting attack, what does the attacker inject into the response headers?

• A. HTML code
• B. New lines
• C. SQL commands
• D. JavaScript

Answer: (B)

During an HTTP Response Splitting attack, the attacker injects new lines into the response headers. This technique exploits the way certain web servers and programming languages parse headers, allowing an attacker to manipulate the HTTP response structure. By injecting new lines, the attacker can create a situation where the server sends multiple HTTP responses instead of just one. This can lead to various malicious outcomes, such as web cache poisoning or cross-site scripting (XSS), as the injected data could later be interpreted by a client browser as legitimate content. This highlights the significance of properly validating and sanitizing input used to construct HTTP headers, as improper handling can lead to severe security vulnerabilities.
