Command Injection

Command injection is a security vulnerability that allows an attacker to execute arbitrary commands on a system by tricking the system into believing that the commands are coming from a trusted source. This can be done by exploiting a vulnerability in a program that accepts user input and does not properly validate it. For example, if a program accepts a filename from a user and then executes the file without first checking to make sure it is a valid file, an attacker could trick the program into executing a malicious file by providing a filename that contains a command to be executed.

Why Learn About Command Injection?

There are many reasons why you might want to learn about command injection. If you are a security professional, you need to be able to understand and mitigate the risks of command injection. If you are a developer, you need to be able to write code that is not vulnerable to command injection. And if you are a user, you need to be aware of the risks of command injection so that you can protect yourself from attacks.
