CVE-2025-4632 is a critical path traversal vulnerability (CWE-22) found in Samsung Electronics MagicINFO 9 Server versions prior to 21.1052. MagicINFO is a digital signage management solution widely used for controlling and scheduling content on display devices. The vulnerability arises due to improper limitation of pathname inputs, allowing an attacker to traverse directories outside the intended restricted directory. This flaw enables an unauthenticated remote attacker to write arbitrary files on the server with system-level privileges. The vulnerability has a CVSS v3.1 base score of 9.8, indicating critical severity, with attack vector being network-based (AV:N), no privileges required (PR:N), no user interaction (UI:N), and full impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Exploitation could lead to complete system compromise, including arbitrary code execution, persistent backdoors, or disruption of digital signage services. Although no known exploits are currently reported in the wild, the ease of exploitation and high impact make this a significant threat. The lack of available patches at the time of reporting further elevates the risk for affected deployments.

For European organizations using Samsung MagicINFO 9 Server, this vulnerability poses a severe risk. Digital signage systems are often integrated into critical infrastructure such as retail environments, transportation hubs, corporate campuses, and public information systems. Successful exploitation could allow attackers to manipulate displayed content, inject malicious payloads, or disrupt services, potentially causing reputational damage, misinformation, or operational outages. The ability to write arbitrary files with system authority also opens the door to lateral movement within networks, data exfiltration, or deployment of ransomware. Given the critical nature of the vulnerability and the lack of authentication or user interaction required, European entities relying on MagicINFO for digital signage management must consider this a high-priority security issue.

Immediate mitigation steps include isolating MagicINFO servers from direct internet exposure and restricting network access to trusted management networks only. Organizations should implement strict input validation and directory access controls at the application and OS levels where possible. Monitoring file system changes and unusual process activity on MagicINFO servers can help detect exploitation attempts early. Since no official patches are currently available, consider deploying virtual patching via web application firewalls (WAFs) configured to block suspicious path traversal patterns. Additionally, conduct thorough audits of MagicINFO server configurations and logs to identify any signs of compromise. Engage with Samsung support channels to obtain updates on patch releases and apply them promptly once available. Finally, develop incident response plans specific to digital signage infrastructure to minimize downtime and impact in case of exploitation.
