       Proper sanitation of input passed to the "frm_title" and "frm_content" 
       parameters is not enforced when adding a new personal agenda item.

       Validation checks on certain HTTP requests are not performed.

       Proper sanitation of input passed to the "title" and "tutor_name" 
       parameters when adding a new course is not enforced before being 
       used. 

       Proper sanitation of input passed to the "student" and "course" 
       parameters in main/mySpace/myStudents.php is not enforced before 
       being used in SQL queries.

       Proper sanitation of input passed to "student" and "course" 
       parameters in main/mySpace/myStudents.php is not enforced before 
       being returned to the user. 

       There are further vulnerabilities caused by unspecified issues. [1]
