CVE-2025-0354 describes a cross-site scripting vulnerability in multiple versions of NEC Corporation's Aterm products. This vulnerability allows an attacker to inject arbitrary scripts via the network, potentially compromising the integrity and confidentiality of affected systems.
The vulnerability has a CVSS score of 4.8, classified as medium severity. This indicates a moderate risk level that organizations must address to protect their networked devices from unauthorized access or manipulation.
Given the nature of this vulnerability, the urgency for defenders is clear. Organizations should prioritize remediation efforts to prevent potential exploitation, as attackers may leverage this vulnerability to conduct attacks.
As of now, the status of CVE-2025-0354 is deferred, and it is not listed in the Known Exploited Vulnerabilities (KEV) catalog. Organizations should monitor updates regarding this vulnerability closely.
Organizations are encouraged to implement security best practices and remain vigilant to safeguard against potential threats stemming from this vulnerability.
Vulnerability Details
The official description identifies a cross-site scripting vulnerability in the following NEC Aterm models: WG2600HS Ver.1.7.2 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 CVSS score of 4.8 indicates medium severity, which reflects potential moderate impacts on confidentiality, integrity, and availability. The attack vector is classified as network-based, requiring high privileges and user interaction.
The vulnerability is categorized under CWE-79, indicating it is related to improper neutralization of input during web page generation.
Technical Analysis
The root cause of this vulnerability stems from inadequate input validation, allowing attackers to inject malicious scripts into web pages viewed by other users. The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely.
The attack complexity is low, suggesting that the vulnerability can be exploited easily. The requirements for high privileges may limit access to certain user accounts, but the necessity for user interaction implies that an attacker must trick users into visiting a malicious link.
The confidentiality impact is rated as low, meaning that unauthorized access to sensitive data may be limited. The integrity impact is also low, indicating that the attacker may not cause significant damage, but could still alter web content in harmful ways.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive user information and the possible compromise of the integrity of web applications. The blast radius for this vulnerability could extend to all users interacting with the affected Aterm products, leading to widespread exploitation.
Given its medium CVSS score and the current lack of known exploitation, organizations should address this vulnerability in their priority patch cycle. Monitoring for updates from NEC and implementing security measures will help mitigate the risks associated with this vulnerability.
