Description
Guardian language-system passes the id GET parameter directly into an unsanitized SQL query in job_info.php (line 16): SELECT * FROM jobs where id = '\".$_GET['id'].\"'. No authentication is required. An unauthenticated attacker can perform error-based SQL injection to extract the database version, current user, schema names, and table contents.
