Code execution vulnerabilities arise when user-controlled data is not adequately filtered or escaped, allowing attackers to inject and execute arbitrary code. This section covers the foundational concepts of code injection, including techniques to identify and exploit these vulnerabilities. By using PHP as an example, we illustrate how to break out of code syntax and inject commands, leveraging functions like `system()` and `eval()` to demonstrate the potential impact.

The course also emphasizes the importance of understanding the language used by the application. Techniques such as using comments, string concatenation, and time-based detection are explored to confirm the presence of code injection. Through practical examples and detailed explanations, you'll learn how to perform ethical hacking to uncover these critical security issues.
