The vulnerability identified as CVE-2025-20016 pertains to an OS command injection vulnerability in the network storage servers STEALTHONE D220/D340/D440 produced by Y'S Corporation. This flaw allows users with administrative privileges, once logged into the web management interface, to execute arbitrary operating system commands. Such a capability poses a significant risk to system integrity and confidentiality.
Classified with a CVSS score of 7.2, the vulnerability is deemed high severity due to its potential impact and ease of exploitation. The attack vector is network-based, and the complexity is low, which means that attackers can exploit this vulnerability without extensive effort or resources. Organizations utilizing these devices must recognize the urgency of this issue and take immediate action.
Risk to organizations includes unauthorized system access and control, leading to potential data breaches and operational disruptions. Given that the vulnerability is currently deferred, it remains critical for organizations to stay informed about updates and patches provided by Y'S Corporation.
Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability and ensure the security of their network storage solutions.
Vulnerability Details
The official CVE description indicates that an OS command injection vulnerability exists in the affected products. This vulnerability falls under the CWE-78 classification, which pertains to OS command injection flaws that allow attackers to execute arbitrary commands on a host system.
The CVSS score of 7.2 indicates a high severity level, reflecting the potential for serious impact due to exploitation. The vulnerability is applicable to all versions of the STEALTHONE D220/D340/D440 products prior to the vendor patch.
This vulnerability was published on January 14, 2025, and has undergone modifications as recently as April 15, 2026. Organizations utilizing these storage servers should remain vigilant for updates from Y'S Corporation regarding this vulnerability.
Technical Analysis
The root cause of this vulnerability lies in improper input validation, which allows an attacker with administrative access to send specially crafted OS commands through the web management interface. The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely.
The attack complexity is classified as low, requiring minimal effort from the attacker to exploit the vulnerability. Privileges required are high, as an attacker must have administrative access to the system. User interaction is not required, making exploitation straightforward for a malicious actor.
If successfully exploited, the impact on confidentiality, integrity, and availability is categorized as high, potentially leading to significant data breaches, unauthorized access, and system downtime.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is considerable, as it allows unauthorized users to execute commands on the server. Organizations utilizing the STEALTHONE storage solutions are at risk of significant operational impacts, including data loss and service disruptions.
This vulnerability's urgency is assessed as high, given its potential for exploitation. Organizations should address this vulnerability in their priority patch cycle to avoid the consequences of a successful attack.
The blast radius is also significant, as successful exploitation could lead to a complete compromise of networked resources, affecting not just the isolated servers but potentially extending to connected systems.
