OWASP Damn Vulnerable Web Sockets (DVWS) is a deliberately vulnerable web application designed for educational and testing purposes that implements WebSocket communication between client and server. The application follows a similar structure to DVWA (Damn Vulnerable Web Application) and contains multiple security vulnerabilities specifically related to WebSocket implementations. It serves as a training platform for security professionals to practice identifying and exploiting WebSocket-related vulnerabilities in a controlled environment. DVWS requires a LAMP stack setup with Apache, PHP, and MySQL, along with PHP MySQLi support. The application also depends on Ratchet and ReactPHP-MySQL libraries, which must be installed using Composer. Configuration involves setting up database connection parameters in the includes/connect-db.php file and creating a hosts file entry pointing dvws.local to the application's IP address. The application runs a WebSocket server through the ws-socket.php script with configurable heartbeat intervals. Users can access the setup interface to complete the initial configuration and begin exploring the various vulnerabilities present in the WebSocket implementation.
