EgiX has discovered a vulnerability in Achievo, 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 atk/attributes/fck/editor/filemanager/browser/mcpuk/connectors/php/connector.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 product's top directory.
The vulnerability is confirmed in version 1.3.2 and reported in version 1.2.0 to 1.3.1.
Solution: Update to version 1.3.3.
