CVE-2024-14007 1 Tvt 1 Nvms-9000 Firmware 2025-11-25 N/A
Shenzhen TVT Digital Technology Co., Ltd. NVMS-9000 firmware (used by many white-labeled DVR/NVR/IPC products) versions prior to 1.3.4 contain an authentication bypass in the NVMS-9000 control protocol. By sending a single crafted TCP payload to an exposed NVMS-9000 control port, an unauthenticated remote attacker can invoke privileged administrative query commands without valid credentials. Successful exploitation discloses sensitive information including administrator usernames and passwords in cleartext, network and service configuration, and other device details via commands such as queryBasicCfg, queryUserList, queryEmailCfg, queryPPPoECfg, and queryFTPCfg.
CVE-2018-25126 1 Tvt 1 Nvms-9000 Firmware 2025-11-25 N/A
Shenzhen TVT Digital Technology Co., Ltd. NVMS-9000 firmware (used by many white-labeled DVR/NVR/IPC products) contains hardcoded API credentials and an OS command injection flaw in its configuration services. The web/API interface accepts HTTP/XML requests authenticated with a fixed vendor credential string and passes user-controlled fields into shell execution contexts without proper argument sanitization. An unauthenticated remote attacker can leverage the hard-coded credential to access endpoints such as /editBlackAndWhiteList and inject shell metacharacters inside XML parameters, resulting in arbitrary command execution as root. The same vulnerable backend is also reachable in some models through a proprietary TCP service on port 4567 that accepts a magic GUID preface and base64-encoded XML, enabling the same command injection sink. Firmware releases from mid-February 2018 and later are reported to have addressed this issue. Exploitation evidence was observed by the Shadowserver Foundation on 2025-01-28 UTC.
CVE-2025-34036 1 Tvt 60 Td-2004ts-cl, Td-2004ts-cl-c, Td-2004ts-cl-c Firmware and 57 more 2025-11-20 9.8 Critical
An OS command injection vulnerability exists in white-labeled DVRs manufactured by TVT, affecting a custom HTTP service called "Cross Web Server" that listens on TCP ports 81 and 82. The web interface fails to sanitize input in the URI path passed to the language extraction functionality. When the server processes a request to /language/[lang]/index.html, it uses the [lang] input unsafely in a tar extraction command without proper escaping. This allows an unauthenticated remote attacker to inject shell commands and achieve arbitrary command execution as root. Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-06 UTC.
CVE-2019-20085 1 Tvt 2 Nvms-1000, Nvms-1000 Firmware 2025-11-07 7.5 High
TVT NVMS-1000 devices allow GET /.. Directory Traversal
CVE-2013-6023 1 Tvt 2 Dvr, Dvr Firmware 2025-04-11 N/A
Directory traversal vulnerability in the TVT TD-2308SS-B DVR with firmware 3.2.0.P-3520A-00 and earlier allows remote attackers to read arbitrary files via .. (dot dot) in the URI.
CVE-2024-7339 2 Provision-isr, Tvt 12 Sh-4050a5-5l\(mm\), Sh-4050a5-5l\(mm\) Firmware, Avision Av108t and 9 more 2024-12-20 5.3 Medium
A vulnerability has been found in TVT DVR TD-2104TS-CL, DVR TD-2108TS-HP, Provision-ISR DVR SH-4050A5-5L(MM) and AVISION DVR AV108T and classified as problematic. This vulnerability affects unknown code of the file /queryDevInfo. The manipulation leads to information disclosure. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. VDB-273262 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
