The Apache Commons FileUpload component can be used to add a file upload capability to your applications.
A flaw was found in the way the DiskFileItem class handled NULL characters in file names. A remote attacker able to supply a serialized instance of the DiskFileItem class, which will be deserialized on a server, could use this flaw to write arbitrary content to any location on the server that is accessible to the user running the application server process. (CVE-2013-2186)
