NTC 6200: Improper Neutralization of Special Elements used in a Command
CVE-2025-4010 is a high-severity improper neutralization of special elements used in a command vulnerability in NTC 6200 from Netcomm, with a CVSS 4.0 base score of 8.6 out of 10. It can be exploited from the same local network by an attacker with a low-privileged account, without any action from a user. Affected NTC 6200 versions: 0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.55% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update NWL-222 to 2.1.21.1 or a later version.
- Read the advisory on onekey.com for workarounds and exact fixed builds.

Official description
The Netcom NTC 6200 and NWL 222 series expose a web interface to be configured and set up by operators. Multiple endpoints of the web interface are vulnerable to arbitrary command injection and use insecure hardcoded passwords. Remote authenticated attackers can gain arbitrary code execution with elevated privileges.

The underlying weakness: Improper Neutralization of Special Elements used in a Command
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- If possible, ensure that all external commands called from the program are statically created.
- Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
