What is CVE-2018-25126?

The NVMS-9000 firmware by Shenzhen TVT Digital Technology is susceptible to a serious security flaw involving hardcoded API credentials and an OS command injection vulnerability. This vulnerability allows unauthenticated attackers to exploit fixed vendor credentials to access specific endpoints, where they can inject malicious commands via user-controlled XML parameters. The flaw lies in the lack of proper input sanitization in the API, enabling remote command execution with root privileges. Additional risks arise from a TCP service on port 4567, which can also be manipulated to exploit the command injection vulnerability. It's crucial for users to upgrade to firmware versions released after mid-February 2018 to mitigate these risks.

Affected Version(s)
