CRLF is the acronym used to refer to Carriage Return (\r) Line Feed (\n). As one might notice from the symbols in the brackets, “Carriage Return” refers to the end of a line, and “Line Feed” refers to the new line. Hence, both CR and LF are used to denote the ending point of a line. When a user requests content on a website, the server returns the website content along with the HTTP headers. The headers and the contents are separated by a defined combination of CR and LF. It is because of CRLF that a server knows where a new header begins or ends. A Carriage Return Line Feed (CRLF) Injection vulnerability is a type of Server Side Injection which occurs when an attacker inserts the CRLF characters in an input field to deceive the server by making it think that an object has terminated and a new one has begun. This happens when the web application doesn’t sanitize user input for CRLF characters. It has a medium severity rating (P3 according to Bugcrowd’s VRT)....
