CVE-2025-54454 is a critical security vulnerability identified in Samsung Electronics MagicINFO 9 Server versions prior to 21.1080.0. The vulnerability is classified under CWE-798, which pertains to the use of hard-coded credentials within software. Specifically, MagicINFO 9 Server contains embedded credentials that are hard-coded into the application, allowing an attacker to bypass authentication mechanisms without needing valid user credentials. This flaw enables remote attackers to gain unauthorized access to the MagicINFO server over the network without any user interaction or prior authentication. The CVSS v3.1 base score of 9.1 reflects the high severity of this vulnerability, highlighting its ease of exploitation (network attack vector, no privileges required, no user interaction) and its significant impact on confidentiality and integrity, though availability is not affected. Exploiting this vulnerability could allow attackers to fully compromise the MagicINFO server, access sensitive data, manipulate digital signage content, or pivot to other internal systems. As of the publication date, no known exploits have been reported in the wild, but the critical nature and straightforward exploitation path make it a high-risk issue requiring immediate attention. MagicINFO 9 Server is a digital signage management solution widely used by enterprises and public institutions to control and distribute multimedia content across display networks. The presence of hard-coded credentials undermines the fundamental security model of the product, exposing organizations to potential espionage, data leakage, and operational disruption risks.

For European organizations, the impact of this vulnerability is substantial. Many enterprises, retail chains, transportation hubs, and public sector entities across Europe utilize Samsung MagicINFO for managing digital signage infrastructure. Unauthorized access could lead to the exposure of sensitive corporate or customer information, manipulation of public-facing content (e.g., displaying misleading or malicious messages), and potential reputational damage. Furthermore, attackers gaining foothold through MagicINFO servers could use them as a pivot point to infiltrate internal networks, escalating the risk of broader compromise. In critical infrastructure sectors such as transportation, healthcare, and government services, compromised digital signage could disrupt operations or be leveraged for misinformation campaigns. The vulnerability's network-based exploitation and lack of required authentication increase the likelihood of attacks, especially in environments where MagicINFO servers are exposed or insufficiently segmented from external networks.

To mitigate this vulnerability effectively, European organizations should: 1) Immediately upgrade MagicINFO 9 Server to version 21.1080.0 or later once Samsung releases a patch or updated version addressing the hard-coded credentials issue. 2) Until a patch is available, restrict network access to MagicINFO servers by implementing strict firewall rules limiting connections to trusted management hosts and internal networks only. 3) Conduct thorough audits of MagicINFO server configurations to identify and remove any default or hard-coded credentials, replacing them with unique, strong passwords where possible. 4) Employ network segmentation to isolate MagicINFO servers from critical infrastructure and sensitive data repositories to limit lateral movement in case of compromise. 5) Monitor network traffic and server logs for unusual authentication attempts or access patterns indicative of exploitation attempts. 6) Engage in proactive threat hunting and incident response planning tailored to digital signage infrastructure. 7) Collaborate with Samsung support channels to obtain official guidance and updates regarding this vulnerability.
