Command Injection
Command Injection is a type of cyber attack where a malicious person inserts commands into a computer program that is then executed by the operating system. The attacker can do this by inputting special characters or code into a program’s input fields, like text boxes.
Once the program has accepted the attacker’s code, the operating system executes it as if it was a legitimate command. This allows the attacker to execute malicious commands, like deleting files, stealing data, or taking control of the entire system.
To avoid command injection attacks, developers should ensure that their programs properly validate and sanitize user input, and limit the use of external commands within the program. It’s important to only accept data and commands that are known to be safe, and to restrict user access and privileges to limit the potential damage of an attack.
