Calvin, a software developer, uses a feature that helps him auto-generate the content of a web page without manual involvement and is integrated with SSI directives. This leads to a vulnerability in…

CRLF injection involves injecting Carriage Return (CR) and Line Feed (LF) characters to manipulate HTTP headers or log entries, not to execute server-side commands via directives.

Server-side template injection targets template engines (e.g., Jinja2, Twig) to execute malicious code within the template context, which is different from exploiting SSI directives.

Server-side JS injection typically refers to vulnerabilities in server-side JavaScript environments, such as Node.js, allowing code execution often through insecure deserialization or evaluation functions, not through SSI directives.

Server-side includes (SSI) injection occurs when a web application insecurely processes user-supplied input as part of a web page that is parsed by an SSI processor. By injecting malicious SSI directives, attackers can force the server to execute arbitrary commands, access sensitive files, or alter the web application's behavior. The scenario specifically mentions the use of 'SSI directives' and the ability to pass 'malicious SSI directives as input values' to modify server files.
