What is Vulnerable File Reader Server?
This MCP is a Python-based server intentionally designed with security flaws to demonstrate command injection vulnerabilities. It allows users to read files via a web interface, but its core function is vulnerable because it executes shell commands directly with user input without proper sanitization. The server showcases how such vulnerabilities can be exploited to run arbitrary commands on the host system, emphasizing the importance of secure coding practices. It is mainly used for educational purposes, security training, and awareness, helping developers understand the risks of insecure input handling and the need for robust validation and sanitization methods.
