CVE-2025-54451 is a critical security vulnerability identified in Samsung Electronics MagicINFO 9 Server versions prior to 21.1080.0. The vulnerability is classified under CWE-94, which pertains to improper control of code generation, commonly known as code injection. This flaw allows an unauthenticated remote attacker to inject and execute arbitrary code on the affected MagicINFO 9 Server without requiring any user interaction. The CVSS v3.1 base score of 9.8 reflects the severity, indicating high impact on confidentiality, integrity, and availability. The attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). Successful exploitation could lead to full system compromise, enabling attackers to execute arbitrary commands, manipulate or exfiltrate sensitive data, disrupt digital signage services, or pivot within the network. MagicINFO 9 Server is a digital signage management platform widely used in enterprise environments to control and distribute content across multiple display devices. The lack of authentication and the ability to execute arbitrary code remotely make this vulnerability particularly dangerous, as it can be exploited by attackers to gain persistent access or disrupt critical signage infrastructure.

For European organizations, the impact of this vulnerability is significant, especially for sectors relying heavily on digital signage for communication, advertising, or operational purposes, such as retail, transportation, hospitality, and public services. Compromise of MagicINFO servers could lead to unauthorized content display, misinformation, or service outages, damaging brand reputation and customer trust. Additionally, since the vulnerability allows full system compromise, attackers could use the affected servers as footholds to infiltrate broader corporate networks, potentially accessing sensitive corporate data or disrupting other critical IT services. Given the criticality and ease of exploitation, organizations face risks of data breaches, operational disruption, and potential regulatory penalties under GDPR if personal data is exposed or mishandled due to the attack.

To mitigate this vulnerability, European organizations should immediately upgrade MagicINFO 9 Server to version 21.1080.0 or later, where the issue is resolved. If immediate patching is not feasible, organizations should implement network-level controls such as isolating MagicINFO servers within segmented VLANs and restricting access via firewalls to trusted management IPs only. Employing intrusion detection/prevention systems (IDS/IPS) to monitor and block suspicious traffic targeting MagicINFO servers is recommended. Additionally, organizations should audit existing MagicINFO deployments for unauthorized access or signs of compromise and enforce strict access controls and monitoring on these servers. Regular backups and incident response plans tailored to digital signage infrastructure should be updated to include this threat. Finally, vendors and integrators should be engaged to ensure secure configuration and timely updates.
