Command Injection Attack
Command Injection Attack is a type of cyber attack where an attacker injects malicious code into a computer system through a vulnerable application. In a typical command injection attack, the attacker exploits a flaw in an application that allows them to insert malicious code that can be executed by the server.
The attacker can use this code to execute arbitrary commands on the server, giving them complete control over the system. This can include accessing sensitive data, modifying or deleting files, or even taking control of the entire system.
Command Injection Attacks are often carried out through web applications that are vulnerable to input validation vulnerabilities. By injecting malicious code into an input field, attackers can execute commands on the server and gain access to sensitive data.
To protect against Command Injection Attacks, developers should implement proper input validation and sanitization techniques in their code. By validating user inputs and ensuring that they only contain safe characters, developers can prevent malicious code from being injected into the system. Additionally, developers should use secure coding practices and regularly update their applications to patch any known vulnerabilities.
In summary, Command Injection Attack is a dangerous cyber attack that can give attackers complete control over a vulnerable system. By properly validating and sanitizing user inputs, developers can prevent this type of attack from occurring and ensure the security of their applications.
