CVE-2025-54453 is a high-severity vulnerability classified as CWE-22, indicating an improper limitation of a pathname to a restricted directory, commonly known as a path traversal vulnerability. This flaw exists in Samsung Electronics MagicINFO 9 Server versions prior to 21.1080.0. MagicINFO 9 Server is a digital signage management platform used to control and distribute content across multiple display devices. The vulnerability allows an attacker with at least low-level privileges (PR:L) to perform a path traversal attack by manipulating file path inputs, bypassing directory restrictions. This can lead to unauthorized code injection, enabling the attacker to execute arbitrary code on the server. The CVSS 3.1 base score of 8.8 reflects the severity, with network attack vector (AV:N), low attack complexity (AC:L), no user interaction (UI:N), and impacts on confidentiality, integrity, and availability (all high). Exploitation does not require user interaction but does require some level of privileges, which suggests that an attacker must have some authenticated access or leverage another vulnerability to gain initial access. Although no known exploits are currently reported in the wild, the potential for code injection makes this vulnerability critical to address promptly. The lack of available patches at the time of publication increases the urgency for organizations to implement compensating controls. Given the nature of MagicINFO as a server managing digital signage content, exploitation could allow attackers to manipulate displayed content, exfiltrate sensitive data, or disrupt service availability, impacting business operations and reputation.

For European organizations using Samsung MagicINFO 9 Server, this vulnerability poses significant risks. Compromise could lead to unauthorized access to internal networks if the server is connected to corporate infrastructure, potentially serving as a pivot point for further attacks. Confidentiality breaches could expose sensitive corporate or customer data managed or transmitted via the signage system. Integrity impacts include unauthorized modification of displayed content, which could be exploited for misinformation, fraud, or reputational damage. Availability impacts could disrupt critical communication channels, especially in sectors relying on digital signage for operational or safety messages, such as transportation hubs, retail, healthcare, and public institutions. The requirement for some privilege level to exploit means insider threats or attackers who have gained initial footholds could leverage this vulnerability to escalate their access and control. The absence of known exploits suggests a window of opportunity for proactive defense, but also the potential for rapid exploitation once public details are widely known. European organizations must consider the regulatory implications of data breaches under GDPR, which could lead to significant fines and legal consequences if personal data is compromised through this vulnerability.

1. Immediate upgrade to Samsung MagicINFO 9 Server version 21.1080.0 or later once patches are released by the vendor. 2. Until patches are available, restrict network access to the MagicINFO server using firewalls and network segmentation to limit exposure only to trusted management networks. 3. Implement strict access controls and monitor user privileges to ensure only authorized personnel have access to the MagicINFO server, minimizing the risk of privilege abuse. 4. Employ application-layer filtering or web application firewalls (WAFs) to detect and block path traversal attempts targeting the server. 5. Conduct regular audits and monitoring of server logs for unusual file access patterns or code injection indicators. 6. Use intrusion detection/prevention systems (IDS/IPS) tuned to detect exploitation attempts related to path traversal and code injection. 7. Educate administrators and users on the risks and signs of exploitation to improve early detection. 8. Develop and test incident response plans specific to digital signage infrastructure compromise to reduce downtime and impact in case of an incident.
