CWE
- CWE-170 - Improper Null Termination
Summary
The NPort 6100-G2/6200-G2 Series is affected by a high-severity vulnerability (CVE-2025-2026) that allows remote attackers to execute a null byte injection through the device’s web API. This may lead to an unexpected device reboot and result in a denial-of-service (DoS) condition.
An authenticated remote attacker with web read-only privileges can exploit the vulnerable API to inject malicious input. Successful exploitation may cause the device to reboot, disrupting normal operations and causing a temporary denial of service.

CWE
- CWE-250 - Execution with Unnecessary Privileges
Summary
The NPort 6100-G2/6200-G2 Series is affected by an execution with unnecessary privileges vulnerability (CVE-2025-1977) that allows an authenticated user with read-only access to perform unauthorized configuration changes through the MCC (Moxa CLI Configuration) tool. The issue can be exploited remotely over the network with low-attack complexity and no user interaction but requires specific system conditions or configurations to be present. Successful exploitation may result in changes to device settings that were not intended to be permitted for the affected user role, potentially leading to a high impact on the confidentiality, integrity, and availability of the device. No impact on other systems has been identified.
