CVE-2025-0355 is a high-severity vulnerability categorized under the CVSS score of 7.5, indicating a significant risk to affected systems. This vulnerability allows attackers to access critical functions without proper authentication, specifically targeting a range of NEC Corporation Aterm devices. The affected models include Aterm 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.
The vulnerability, classified as Missing Authentication for Critical Function, poses a risk to organizations as attackers may leverage this weakness to obtain Wi-Fi passwords via the network, leading to unauthorized access and potential network breaches. As this vulnerability has been deferred, it is crucial for organizations using affected devices to remain vigilant and monitor for any updates regarding patches or remediation strategies.
Organizations should prioritize patching immediately. The absence of a confirmed public exploit at this time does not diminish the urgency for remediation, as the risk remains significant given the potential for exploitation once the vulnerability is made public.
Given the current threat landscape, organizations must proactively assess their environments and implement necessary security measures to prevent unauthorized access to critical functionalities.
Vulnerability Details
The CVE-2025-0355 vulnerability is described as follows: Missing Authentication for Critical Function vulnerability in NEC Corporation Aterm devices allows an attacker to obtain a Wi-Fi password via the network.
The vulnerability was published on January 15, 2025, and has a CVSS 3.1 score of 7.5, indicating a high severity classification. The lack of authentication enables unauthorized access, with a significant confidentiality impact and no integrity or availability impact.
Technical Analysis
The root cause of this vulnerability lies in the lack of authentication mechanisms for critical functions within the affected devices. Attackers can exploit this weakness remotely, with no privileges required and no user interaction necessary, leading to a low attack complexity.
The attack vector is network-based, allowing attackers to potentially acquire sensitive information such as Wi-Fi passwords. The high confidentiality impact indicates that successful exploitation can lead to unauthorized network access, further compromising the security of connected devices.
Risk & Impact Analysis
Risk to organizations includes the possibility of unauthorized access to networks, which may facilitate additional attacks such as data breaches or service disruptions. The blast radius potential is significant, particularly in environments where these devices are deployed widely.
The urgency for remediation is high given the potential for exploitation. Organizations must assess the risk and implement necessary security measures to mitigate exposure to this vulnerability.
