DESCRIPTION:
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.

The vulnerability is confirmed in version 10.1.007. Other versions
may also be affected.

SOLUTION:
Restrict access to the admin/code/tce_functions_tcecode_editor.php
script (e.g. via .htaccess).
