Summary

CVE-2025-0356 is a high-severity OS Command Injection (CWE-78) vulnerability in Nec (inferred from references). Its CVSS base score is 7.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 43.4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2025-0356 is a command injection vulnerability (CWE-78) affecting NEC Corporation Aterm WX1500HP versions 1.4.2 and earlier, and WX3600HP versions 1.5.3 and earlier. These are network devices that allow an attacker to execute arbitrary OS commands via the network. The vulnerability was published on 2025-01-15 and carries a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).

Exploitation requires high privileges (PR:H), such as those held by an authenticated administrator, but can be performed remotely over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Successful exploitation grants the attacker the ability to run arbitrary OS commands, leading to high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H) within the unchanged scope (S:U).

NEC has published a security advisory with mitigation guidance at https://jpn.nec.com/security-info/secinfo/nv25-003_en.html. Security practitioners should consult this reference for details on patches or workarounds.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-2 Flaw Remediation good match
prevent

Directly mitigates the command injection vulnerability by requiring timely identification, reporting, and patching of the specific flaw in the NEC Aterm devices.

SI-10 Information Input Validation good match
prevent

Prevents command injection (CWE-78) by enforcing validation of all network inputs to block arbitrary OS command execution.

AC-6 Least Privilege partial match
prevent

Limits exploitation risk by restricting high privileges (PR:H) required for the attack to only necessary personnel or processes on the network device.
