Summary

CVE-2025-0355 is a high-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Nec (inferred from references). Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 38.3th 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 AC-14 (Permitted Actions Without Identification or Authentication) and AC-3 (Access Enforcement).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-14 Permitted Actions Without Identification or Authentication good match

prevent

AC-14 directly restricts permitted actions without identification or authentication, preventing exposure of critical functions like Wi-Fi password retrieval.

SC-14 Public Access Protections good match

prevent

SC-14 protects sensitive information at publicly accessible unauthenticated interfaces, directly mitigating network-based retrieval of the Wi-Fi password.

AC-3 Access Enforcement good match

prevent

AC-3 enforces approved access authorizations, ensuring authentication is required for sensitive configuration data like Wi-Fi passwords.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

Why these techniques?

Missing authentication on a network-exposed critical function in routers directly enables remote unauthenticated retrieval of Wi-Fi credentials via exploitation of the public-facing device interface.

Deeper analysisAI

CVE-2025-0355 is a Missing Authentication for Critical Function vulnerability (CWE-306) in multiple NEC Corporation Aterm router models, including WG2600HS Ver.1.7.2 and earlier, WF1200CRS Ver.1.6.0 and earlier, WG1200CRS Ver.1.5.0 and earlier, GB1200PE Ver.1.3.0 and earlier, WG2600HP4 Ver.1.4.2 and earlier, WG2600HM4 Ver.1.4.2 and earlier, WG2600HS2 Ver.1.3.2 and earlier, WX3000HP Ver.2.4.2 and earlier, and WX4200D5 Ver.1.2.4 and earlier. Published on 2025-01-15, the issue has a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high confidentiality impact with no requirements for authentication or user interaction.

A network-accessible attacker can exploit this vulnerability remotely without privileges to retrieve the Wi-Fi password. The lack of authentication for a critical function enables unauthorized access to sensitive configuration data over the network.
