Summary

CVE-2025-54446 is a critical-severity Path Traversal (CWE-22) vulnerability in Samsung Magicinfo 9 Server. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 26.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SC-7 (Boundary Protection) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2025-54446 is an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability, mapped to CWE-22, in Samsung Electronics MagicINFO 9 Server. It affects versions less than 21.1080.0 and enables attackers to upload a web shell to the web server due to inadequate path validation.

With 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), the vulnerability is highly severe and remotely exploitable over the network by unauthenticated attackers with low complexity and no user interaction required. Successful exploitation allows uploading and executing a web shell, granting high-impact control over confidentiality, integrity, and availability of the affected server.

Samsung's security advisory at https://security.samsungtv.com/securityUpdates provides details on mitigation. Practitioners should upgrade to MagicINFO 9 Server version 21.1080.0 or later, where the issue is addressed.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly requires validation of untrusted file path inputs in uploads to block path traversal sequences like '../' and prevent web shell placement outside restricted directories.

SC-7 Boundary Protection good match
prevent

Boundary protection at web server interfaces enables inspection and blocking of path traversal payloads in remote upload requests via WAF or similar mechanisms.

AC-3 Access Enforcement partial match
prevent

Enforces logical access controls on directories to restrict unauthorized writes, mitigating damage even if partial path traversal occurs.
