Database query manipulation via concatenated high-score fields
Published Dec 19, 2022 · Updated Apr 15, 2025
SQL injection in Platzh1rsch Pacman Canvas 1.0.0 through 1.0.5 allows remote authenticated users to manipulate database queries. The addHighscore function in data/db-handler.php directly concatenates submitted name, score, level, and request metadata into an INSERT statement instead of binding parameters. Low-privileged access to the high-score submission path is required, and successful injection can read or alter records reachable by the database connection.
