An attacker thereby introduces (or "injects") code into the program and changes the course of its execution. The result of successful code injection can be disastrous, for example, by ...
Server-side scripting is a technique used in web development which involves employing scripts on a web server which produces a response customized for each user's (client's) request to the website. Scripts can be written in any of a number of server-side scripting languages that are available. Server-side scripting is distinguished from client ...
