Mail-it Now! Upload2Server is prone to an arbitrary file upload vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input before uploading files.

Successful exploitation will cause the application to execute the file in the security context of the Web server process. This may facilitate unauthorized access; other attacks are also possible.
