What is Command Injection in Cybersecurity?
An attack that executes arbitrary operating system commands on the host through a vulnerable application. It occurs when an application passes unsafe user input directly to a system shell. Successful command injection gives the attacker the same privileges as the application's service account.
Why Command Injection Matters for Your Cybersecurity Career
Command injection often leads directly to full server compromise, making it a top priority for cybersecurity professionals. Penetration testers test for command injection alongside SQL injection and XSS. Security engineers prevent it by avoiding shell calls and using strict input validation. OWASP ranks injection flaws as a perennial top-ten risk.
