Vulnerable:
Yes
Security database references:

More information:

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.

For the oldstable distribution (squeeze), this problem has been fixed in version 1.2.2-1+deb6u1.

For the stable distribution (wheezy), this problem has been fixed in version 1.2.2-1+deb7u1.
