CVE-2025-20617 describes a high-severity vulnerability in UD-LT2 firmware versions 1.00.008_SE and earlier. This vulnerability allows for improper neutralization of special elements used in an OS command, commonly known as OS Command Injection. If an attacker gains administrative access to the affected product and manipulates requests for a specific screen operation, they can execute arbitrary OS commands on the underlying operating system. The potential for exploitation is significant, as successful attacks could lead to unauthorized access and control over critical system functions.
The vulnerability has been assigned a CVSS score of 7.2, categorizing it as high severity. This score reflects the risk to organizations, where an attacker can exploit the vulnerability with low complexity and high privileges. The attack vector is classified as network-based, meaning that an attacker can exploit it remotely, further increasing the urgency for organizations to address this issue.
Organizations should prioritize patching this vulnerability immediately to prevent potential exploitation. The consequences of an attack could lead to severe breaches in confidentiality, integrity, and availability, emphasizing the critical nature of addressing this vulnerability as part of a comprehensive security strategy.
As of now, this vulnerability has not been included in the Known Exploited Vulnerabilities (KEV) catalog, indicating that there are no confirmed instances of active exploitation. However, this does not diminish the importance of prompt remediation efforts. The ongoing monitoring of the vulnerability landscape is essential, as changes may impact its status and exposure in the future.
Organizations utilizing UD-LT2 firmware must assess their deployment and implement necessary updates to mitigate the risks associated with this vulnerability.
Vulnerability Details
The official description states that the improper neutralization of special elements used in an OS command ('OS Command Injection') issue exists in UD-LT2 firmware Ver.1.00.008_SE and earlier. The vulnerability is categorized under CWE-78. The CVSS vector string is CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H.
Organizations are encouraged to review their systems for the affected firmware versions and apply patches as soon as they become available.
Technical Analysis
The root cause of CVE-2025-20617 is the failure to properly sanitize user input in the affected firmware, allowing an attacker to inject arbitrary commands into the system. The attack vector is network-based, enabling remote exploitation by an attacker with administrative access. The attack complexity is classified as low since it requires a high privilege level, but user interaction is not required.
The potential impacts of this vulnerability are severe, with high confidentiality, integrity, and availability impacts. Attackers could execute arbitrary commands, compromising system integrity and potentially leading to unauthorized access to sensitive data.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-20617 is significant due to the potential for an attacker to gain control over the affected systems. Organizations must consider the blast radius of a successful exploitation, which could extend beyond the immediate system to other interconnected devices and networks.
Given the high CVSS score, organizations should assess their exposure to this vulnerability and prioritize remediation efforts based on their risk management frameworks. The urgency to address this vulnerability is high, and organizations must implement necessary patches to safeguard their systems.
