http://secunia.com/advisories/30208/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
CMS Made Simple 1.x

DESCRIPTION:
EgiX has discovered a vulnerability in CMS Made Simple, 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 in modules/FileManager/postlet/javaUpload.php, when a file
name has multiple file extensions. This can be exploited to upload
malicious script files inside the web root (e.g. PHP scripts).

Successful exploitation requires a specific server configuration
(e.g. an Apache server with the "mod_mime" module installed) and that
the web server user has write permissions to the
modules/FileManager/postlet directory.

The vulnerability is confirmed in version 1.2.4. Prior versions may
also be affected.

SOLUTION:
Update to version 1.2.5.
