Code injection, also known as remote code execution, is a type of security vulnerability that occurs when an attacker is able to insert and execute malicious code into a target system. This can happen in several ways, including through input fields, cookies, and other user inputs that are not properly validated or sanitized.
Once the attacker is able to inject their code into the target system, they can potentially gain access to sensitive information, modify or delete data, and even take control of the entire system. Code injection attacks can be carried out against web applications, mobile apps, and desktop software.
Examples of code injection attacks include SQL injection, cross-site scripting (XSS), and command injection. To prevent code injection attacks, developers should implement proper input validation and sanitization techniques, as well as use secure coding practices such as parameterized queries and prepared statements. Additionally, regular security audits and penetration testing can help identify and address any vulnerabilities before they can be exploited.
