NUUO NVRmini2 through 3.11 allows an unauthenticated attacker to upload an encrypted TAR archive, which can be abused to add arbitrary users because of the lack of handle_import_user.php authentication. When combined with another flaw (CVE-2011-5325), it is possible to overwrite arbitrary files under the web root and achieve code execution as root.

Directory traversal vulnerability in the BusyBox implementation of tar before 1.22.0 v5 allows remote attackers to point to files outside the current working directory via a symlink.
