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'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.

cgi_system in NUUO's NVRMini2 3.8.0 and below allows remote attackers to execute arbitrary code via crafted HTTP requests.

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 NVRMini2 version 3.9.1 is vulnerable to authenticated remote command injection. An attacker can send crafted requests to upgrade_handle.php to execute OS commands as root.
