Kotlin Command Injection: Examples and Prevention

Command injection is a critical security vulnerability in web applications where an attacker injects malicious code, such as JavaScript or Java, into a server, leading to unauthorized command execution and potential server control. The article explores the concept of command injection, providing examples and illustrating how attackers can exploit applications using vulnerable functions like exec. It emphasizes the importance of mitigating such vulnerabilities by avoiding functions that execute system commands unless absolutely necessary, implementing input sanitization, and utilizing security analysis tools like StackHawk to routinely scan for risks. As developers often prioritize rapid development over security, the piece underscores the necessity of integrating robust security measures into the development process to protect modern web applications.
