NUUO Network Video Recorder 2.0.0 is vulnerable to arbitrary file read. In up.php, the url parameter submitted by the user via POST is received, and fopen() is used to open the URL in binary read-only mode. The content is then written to the /tmp/ directory, with the filename derived from basename() of the URL. This operation requires no authentication.

Command Injection in NUUO Network Video Recorder handle_import_privilege.php

NUUO Network Video Recorder 2.0.0 is vulnerable to Command Injection in handle_import_privilege.php.

Vacron NVR Remote Command Execution

A remote command injection vulnerability exists in Vacron Network Video Recorder (NVR) devices v1.4 due to improper input sanitization in the board.cgi script. The vulnerability allows unauthenticated attackers to pass arbitrary commands to the underlying operating system via crafted HTTP requests. These commands are executed with the privileges of the web server process, enabling remote code execution and potential full device compromise. Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-06 UTC.

NUUO v03.11.00 was discovered to contain access control issue.

NUUO NVRmini 2 deletefile.php path traversal

A vulnerability, which was classified as critical, was found in NUUO NVRmini 2 up to 3.0.8. Affected is an unknown function of the file /deletefile.php. The manipulation of the argument filename leads to path traversal. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The identifier of this vulnerability is VDB-258780.

NUUO Camera deletefile.php denial of service

A vulnerability was found in NUUO Camera up to 20240319 and classified as problematic. This issue affects some unknown processing of the file /deletefile.php. The manipulation of the argument filename leads to denial of service. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The identifier VDB-258197 was assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

NUUO Camera handle_config.php print_file command injection

A vulnerability was found in NUUO Camera up to 20250203. It has been declared as critical. This vulnerability affects the function print_file of the file /handle_config.php. The manipulation of the argument log leads to command injection. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

upgrade_handle.php on NUUO NVRmini devices allows Remote Command Execution via shell metacharacters in the uploaddir parameter for a writeuploaddir command.

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.

Stack-based buffer overflow in cgi-bin/cgi_main in NUUO NVRmini 2 1.7.6 through 3.0.0 and NETGEAR ReadyNAS Surveillance 1.1.2 allows remote authenticated users to execute arbitrary code via the sn parameter to the transfer_license command.

NUUO NVRmini 2 1.7.5 through 3.0.0, NUUO NVRsolo 1.0.0 through 3.0.0, and NETGEAR ReadyNAS Surveillance 1.1.1 through 1.4.1 have a hardcoded qwe23622260 password for the nuuoeng account, which allows remote attackers to obtain sensitive information via an __nvr_status___.php request.

handle_daylightsaving.php in NUUO NVRmini 2 1.7.5 through 3.0.0, NUUO NVRsolo 1.0.0 through 3.0.0, NUUO Crystal 2.2.1 through 3.2.0, and NETGEAR ReadyNAS Surveillance 1.1.1 through 1.4.1 allows remote attackers to execute arbitrary PHP code via the NTPServer parameter.

__debugging_center_utils___.php in NUUO NVRmini 2 1.7.5 through 3.0.0, NUUO NVRsolo 1.7.5 through 3.0.0, and NETGEAR ReadyNAS Surveillance 1.1.1 through 1.4.1 allows remote attackers to execute arbitrary PHP code via the log parameter.

cgi-bin/cgi_system in NUUO NVRmini 2 1.7.5 through 2.x, NUUO NVRsolo 1.7.5 through 2.x, and NETGEAR ReadyNAS Surveillance 1.1.1 through 1.4.1 allows remote attackers to reset the administrator password via a cmd=loaddefconfig action.

NUUO NVRmini 2 1.0.0 through 3.0.0 and NUUO NVRsolo 1.0.0 through 3.0.0 have hardcoded root credentials, which allows remote attackers to obtain administrative access via unspecified vectors.

cgi-bin/cgi_main in NUUO NVRmini 2 1.7.6 through 3.0.0 and NETGEAR ReadyNAS Surveillance 1.1.2 allows remote authenticated users to execute arbitrary commands via shell metacharacters in the sn parameter to the transfer_license command.

NUUO Network Video Recorder NVRsolo v03.06.02 was discovered to contain a reflected cross-site scripting (XSS) vulnerability via login.php.

NUUO Network Video Recorder NVRsolo 3.9.1 is affected by a Cross Site Scripting (XSS) vulnerability. An attacker can steal the user's session by injecting malicious JavaScript codes which leads to session hijacking.

NUUO Network Video Recorder Firmware 1.7.x through 3.3.x allows unauthenticated attackers to execute arbitrary commands via shell metacharacters to handle_load_config.php.

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.
