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.
NUUO NVRmini2 Network Video Recorder firmware through 3.9.1 allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow), resulting in ability to read camera feeds or reconfigure the device.
NUUO's NVRMini2 3.8.0 and below contains a backdoor that would allow an unauthenticated remote attacker to take over user accounts if the file /tmp/moses exists.
