CVE-2025-54448 is an Unrestricted Upload of File with Dangerous Type vulnerability (CWE-434) in Samsung Electronics MagicINFO 9 Server. This flaw allows for code injection and affects versions of MagicINFO 9 Server prior to 21.1080.0. The vulnerability has a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to its potential for high impact on confidentiality, integrity, and availability.

Remote attackers require no authentication, privileges, or user interaction to exploit this vulnerability over the network with low complexity. Successful exploitation enables arbitrary code injection, potentially granting attackers full control over the affected server, including data exfiltration, modification, or disruption of services.

Samsung's security advisory at https://security.samsungtv.com/securityUpdates provides details on mitigation. Security practitioners should upgrade MagicINFO 9 Server to version 21.1080.0 or later to address this issue.

Mitigating Controls (NIST 800-53 r5) AI

Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.

Least functionality restricts the file types and automatic processing capabilities the system will accept.

SC-18 Mobile Code partial match

Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.

finds

Configuration and acceptance testing verify that file-upload handling enforces allowed types and does not permit dangerous content to be stored or executed.

prevents

Secure-coding guidelines and security testing explicitly address restrictions on allowed file types and upload handling, reducing the risk that dangerous file uploads are accepted without validation.

prevents

Mandated testing for malicious content and known vulnerabilities reduces the likelihood that an outsourced component will contain or accept dangerous file types that could later be uploaded or executed.

mitigates

Application allow-listing and pre-use scanning of received files directly blocks the introduction of executable content that has not been vetted, eliminating the primary vector for unrestricted dangerous file uploads.
