Command & Code Injection
Learn to identify and mitigate vulnerabilities related to OS command injection and arbitrary code execution in backend systems.
What is Command & Code Injection?
Welcome! In this lesson, we'll explore Command and Code Injection, two critical backend vulnerabilities.
These attacks trick your application into executing unintended system commands or application-level code, leading to severe security breaches.
- Command Injection: Executes OS commands.
- Code Injection: Executes application programming language code.
OS Command Injection Basics
OS Command Injection occurs when an attacker can run arbitrary operating system commands on the server hosting your application.
This happens when an application passes unsanitized user-supplied input to a system shell, often through functions that execute external programs.
Attackers can then:
- Read, write, or delete files.
- Execute malicious scripts.
- Gain full control over the server.
