John Leitch has discovered a vulnerability in TCExam, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to the admin/code/tce_functions_tcecode_editor.php script allowing the upload of files with arbitrary extensions to a folder inside the webroot. This can be exploited to upload arbitrary files inside the webroot and e.g. execute arbitrary PHP code.
Successful exploitation requires that the "admin" folder has not been protected with an additional authentication system.
The vulnerability is confirmed in version 10.1.007. Other versions may also be affected.
Solution: Update to version 10.1.012.
