Debian Security Advisory DSA-2827-1 email@example.com http://www.debian.org/security/ Salvatore Bonaccorso December 24, 2013 http://www.debian.org/security/faq
Package : libcommons-fileupload-java Vulnerability : arbitrary file upload via deserialization Problem type : local (remote) Debian-specific: no CVE ID : CVE-2013-2186 Debian Bug : 726601
It was discovered that Apache Commons FileUpload, a package to make it easy to add robust, high-performance, file upload capability to servlets and web applications, incorrectly handled file names with NULL bytes in serialized instances. 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.
