Forma LMS on its 3.1.0 version and earlier is vulnerable to a SQL injection vulnerability. The exploitation of this vulnerability could allow an authenticated attacker (with the role of student) to perform a SQL injection on the 'id' parameter in the 'appCore/index.php?r=adm/mediagallery/delete' function in order to dump the entire database or delete all contents from the 'core_user_file' table.
