CVE-2025-54450 is a high-severity vulnerability identified in Samsung Electronics MagicINFO 9 Server versions prior to 21.1080.0. The vulnerability is classified as CWE-22, which corresponds to an 'Improper Limitation of a Pathname to a Restricted Directory,' commonly known as a path traversal vulnerability. This flaw allows an attacker to manipulate file paths to access directories and files outside the intended restricted directory scope. In the context of MagicINFO 9 Server, this vulnerability can be exploited to perform code injection, which means an attacker could potentially execute arbitrary code on the server hosting the MagicINFO application. The CVSS v3.1 base score is 7.2, indicating a high severity level. The vector details (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) show that the attack can be performed remotely over the network with low attack complexity, but requires high privileges (PR:H) and no user interaction (UI:N). The impact on confidentiality, integrity, and availability is high, meaning successful exploitation could lead to full compromise of the affected system. MagicINFO 9 Server is a digital signage management solution widely used for managing and distributing content to digital displays, often deployed in corporate, retail, transportation, and public sector environments. The lack of available patches at the time of publication increases the urgency for organizations to implement mitigations. There are no known exploits in the wild yet, but the potential for code injection makes this vulnerability a significant risk if weaponized.

For European organizations, the impact of this vulnerability could be substantial, especially for those relying on MagicINFO 9 Server for critical digital signage infrastructure. Exploitation could lead to unauthorized access to sensitive content, disruption of digital signage services, and potential lateral movement within the network if attackers gain code execution capabilities. This could affect sectors such as retail chains, transportation hubs (airports, train stations), corporate campuses, and public institutions that use digital signage for communication and operational purposes. The compromise of these systems could result in reputational damage, operational downtime, and potential data breaches if the attacker leverages the code execution to access other internal systems. Given the high privileges required, the threat is more relevant to insiders or attackers who have already gained elevated access, but the network-exposed nature of the service means that privilege escalation could be a stepping stone to full system compromise.

1. Immediate mitigation should include restricting network access to the MagicINFO 9 Server to trusted management networks only, using firewalls and network segmentation to limit exposure. 2. Implement strict access controls and monitor for any unusual privilege escalations or file access patterns on the server. 3. Regularly audit and review user privileges to ensure that only necessary personnel have high-level access to the MagicINFO server. 4. Employ application-layer filtering or Web Application Firewalls (WAFs) that can detect and block path traversal attempts targeting the MagicINFO server. 5. Until an official patch is released, consider deploying virtual patching techniques or disabling any unnecessary file upload or management features that could be exploited. 6. Monitor vendor communications closely for patch releases and apply updates promptly once available. 7. Conduct internal penetration testing focused on path traversal and code injection vectors to identify any other weaknesses in the deployment. 8. Maintain comprehensive logging and alerting on the MagicINFO server to detect potential exploitation attempts early.
