Organizations utilizing affected models should prioritize remediation to mitigate risks associated with this vulnerability.
As of now, this vulnerability is listed as deferred, suggesting that while it is acknowledged, a formal patch may not yet be available. However, organizations should still take proactive measures to secure their systems.
Given the potential impact, it is critical for organizations to review their security posture and apply necessary mitigations.
Vulnerability Details
The official description of the vulnerability states that: NEC Corporation Aterm WX1500HP Ver.1.4.2 and earlier and WX3600HP Ver.1.5.3 and earlier allows an attacker to execute arbitrary OS commands via the network.
This vulnerability is classified as a CWE-78, indicating a command injection issue.
The vulnerability was published on January 15, 2025, and is currently in a deferred status.
Technical Analysis
The root cause of this vulnerability is associated with insufficient input validation, allowing attackers to inject arbitrary OS commands through network inputs.
The attack vector is network-based, allowing remote exploitation without requiring physical access to the devices. The attack complexity is low, making it easier for potential attackers to exploit this vulnerability.
Exploitation requires high privileges, which means that an attacker would need access to an account with elevated permissions to successfully execute arbitrary commands.
Risk & Impact Analysis
Risk to organizations includes unauthorized command execution, which can lead to significant data loss, unauthorized access to sensitive information, and potential service outages. The blast radius for this vulnerability could affect all devices running the specified versions of the Aterm products.
Organizations should assess their exposure to this vulnerability and prioritize remediation efforts accordingly. Given the high CVSS score, it is critical to address this vulnerability in the upcoming patch cycle.
With an EPSS score of 0.00154, this vulnerability has a relatively low probability of exploitation in the wild, but organizations should not underestimate its potential impact.
