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.","dueDate":"","id":"CVE-2018-25126","kev_catalogs":["vulncheck"],"knownRansomwareCampaignUse":"Unknown","product":"NVMS-9000","requiredAction":"Apply remediations or mitigations per vendor instructions or discontinue use of the product if remediation or mitigations are unavailable.","severity":"HIGH","source":"vulncheck_kev","title":"TVT nvms-9000_firmware Improper Neutralization of Special Elements used in an OS Command","vendor":"Shenzhen TVT Digital Technology Co., Ltd."}
