CVE-2025-54445 is a high-severity vulnerability identified in Samsung Electronics MagicINFO 9 Server, specifically versions prior to 21.1080.0. The vulnerability is categorized under CWE-611, which refers to Improper Restriction of XML External Entity (XXE) Reference. This flaw allows an attacker to exploit the XML parser used by the MagicINFO 9 Server to perform Server Side Request Forgery (SSRF). SSRF occurs when an attacker can make the server send crafted requests to internal or external systems, potentially bypassing network controls. In this case, the vulnerability arises because the XML parser does not properly restrict external entity references, enabling malicious XML payloads to cause the server to fetch arbitrary resources or interact with internal services. The CVSS v3.1 score is 8.2, indicating a high severity with the vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N. This means the vulnerability can be exploited remotely over the network without authentication or user interaction, leading to a high impact on confidentiality (potential data disclosure), a limited impact on integrity, and no impact on availability. The vulnerability affects MagicINFO 9 Server, a digital signage management platform widely used for controlling and distributing content to digital displays. The absence of known exploits in the wild suggests that active exploitation has not yet been observed, but the ease of exploitation and potential impact make it a critical issue to address. No official patches or mitigation links were provided at the time of publication, emphasizing the need for immediate attention from affected organizations.

For European organizations using Samsung MagicINFO 9 Server, this vulnerability poses a significant risk. The ability to perform SSRF can allow attackers to access internal network resources that are otherwise protected, potentially leading to unauthorized data disclosure or reconnaissance for further attacks. Given that MagicINFO servers often manage critical digital signage infrastructure in retail, transportation, corporate environments, and public spaces, exploitation could lead to leakage of sensitive configuration or operational data. Although the vulnerability does not directly impact availability, the confidentiality breach could facilitate subsequent attacks such as lateral movement or data exfiltration. European organizations with interconnected internal networks or those relying heavily on MagicINFO for customer-facing digital signage may face reputational damage and operational risks if exploited. The lack of authentication requirements and user interaction lowers the barrier for attackers, increasing the urgency of mitigation.

1. Immediate upgrade: Organizations should prioritize upgrading MagicINFO 9 Server to version 21.1080.0 or later once Samsung releases a patch or update addressing this vulnerability. 2. XML parser configuration: Until a patch is available, administrators should review and harden XML parser settings to disable external entity processing if configurable. 3. Network segmentation: Restrict the MagicINFO server’s network access to only necessary resources, blocking outbound requests to sensitive internal systems to limit SSRF impact. 4. Web application firewall (WAF): Deploy or update WAF rules to detect and block malicious XML payloads targeting XXE vulnerabilities. 5. Monitoring and logging: Enhance logging of XML processing errors and outbound requests from the MagicINFO server to detect suspicious activity early. 6. Incident response readiness: Prepare to respond to potential exploitation attempts by establishing alerting mechanisms and validating backups of critical configurations. 7. Vendor engagement: Maintain communication with Samsung for official patches and security advisories and apply them promptly.
