Definition ∞ Command Injection is a cyber attack where an attacker executes arbitrary commands on a host operating system. This attack occurs when an application passes unsanitized user input to a system shell. Successful command injection allows an attacker to compromise the server and potentially access sensitive data. It represents a significant security weakness in web applications.
Context ∞ Command Injection remains a persistent threat across various digital systems, including those supporting cryptocurrency operations. The ongoing discussion highlights the importance of rigorous input validation and the use of safe APIs to prevent such exploits. Future developments in secure coding practices and automated vulnerability scanning aim to reduce the prevalence of this attack vector.
