The vulnerability EUVD-2025-22412, also known as CVE-2025-54455, pertains to the use of hard-coded credentials in Samsung Electronics MagicINFO 9 Server, which allows for authentication bypass. This vulnerability is rated with a CVSS Base Score of 9.1, indicating a critical severity level. The CVSS vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N breaks down as follows:

• Attack Vector (AV): Network (N) - The vulnerability is exploitable over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal skill or resources.
• Privileges Required (PR): None (N) - No privileges are required to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required.
• Scope (S): Unchanged (U) - The vulnerability does not change the security scope.
• Confidentiality (C): High (H) - There is a high impact on confidentiality.
• Integrity (I): High (H) - There is a high impact on integrity.
• Availability (A): None (N) - There is no impact on availability.

Given the high confidentiality and integrity impacts, this vulnerability poses a significant risk to organizations using the affected software.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector for this vulnerability is network-based. An attacker could exploit the hard-coded credentials to bypass authentication mechanisms, gaining unauthorized access to the MagicINFO 9 Server. Potential exploitation methods include:

• Credential Stuffing: Using the hard-coded credentials to gain access.
• Automated Scripts: Developing scripts to automate the exploitation process, targeting multiple instances of the server.
• Phishing: Tricking users into revealing additional credentials or sensitive information once initial access is gained.

3. Affected Systems and Software Versions

The vulnerability affects Samsung Electronics MagicINFO 9 Server versions less than 21.1080.0. Organizations using these versions are at risk and should prioritize updating to a patched version.

4. Recommended Mitigation Strategies

To mitigate the risk associated with this vulnerability, the following strategies are recommended:

• Patch Management: Immediately update to the latest version of MagicINFO 9 Server (21.1080.0 or higher).
• Credential Management: Ensure that all credentials are regularly updated and follow best practices for password management.
• Network Segmentation: Implement network segmentation to limit the exposure of critical systems.
• Monitoring and Logging: Enhance monitoring and logging to detect any unauthorized access attempts.
• Access Controls: Implement strict access controls and multi-factor authentication (MFA) where possible.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant threat to the European cybersecurity landscape, particularly for organizations that rely on Samsung Electronics' MagicINFO 9 Server for digital signage and content management. The potential for unauthorized access and data breaches could lead to financial losses, reputational damage, and legal consequences under regulations such as GDPR.
