DESCRIPTION:
A vulnerability has been discovered in DoceboLMS, which can be
exploited by malicious users to compromise a vulnerable system.

Input passed to the "message[attach]" POST parameter in index.php
(when "modname" is set to "message", "op" is set to "addmessage",
"from" is set to "out", and "message[subject]" is not empty) is not
properly verified before being used to upload files. This can be
exploited to e.g. upload and execute arbitrary PHP files.

The vulnerability is confirmed in version 4.0.4. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly verified.
