Description
Liz0ziM has discovered a vulnerability in easy-CMS, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to an error in the handling of file uploads where a filename has multiple file extensions. This can be exploited to upload malicious script files inside the web root (e.g. a PHP script) via the choose_file.php script.

Example:
[file].php.gif

Successful exploitation may allow execution of script code depending on the HTTP server configuration (it requires e.g. an Apache server with the "mod_mime" module installed).

The vulnerability has been confirmed in version 0.1.2. Other versions may also be affected.

Solution
Edit the source code to ensure that files with multiple file extensions cannot be uploaded.
