A.

B.

D.

Explanation:
HTTP header injection is a general class of web application security vulnerability which occurs when Hypertext Transfer Protocol (HTTP) headers are
dynamically generated based on user input. Header injection in HTTP responses can allow for HTTP response splitting, Session fixation via the Set-Cookie header,
cross-site scripting (XSS), and malicious redirect attacks via the location header. HTTP header injection is a relatively new area for web-based attacks, and has
primarily been pioneered by Amit Klein in his work on request/response smuggling/splitting.
Header manipulation is the insertion of malicious data, which has not been validated, into a HTTP response header. One example of header manipulation is a HTTP response splitting attack. This type of attack exploits applications that allow a carriage return or line feed as input.
