Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
SI-10 requires information input validation at upload entry points, directly preventing path traversal by ensuring pathnames cannot escape restricted directories in MagicINFO Server.
AC-3 enforces logical access controls on file system resources, blocking unauthorized writes to restricted directories even if path traversal occurs.
SC-7 provides boundary protection with content inspection at the web server interface to filter and block path traversal sequences in remote upload requests.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Path traversal in public-facing server directly enables unauthenticated web shell upload for RCE.

Deeper analysisAI
CVE-2025-54438, published on 2025-07-23, is an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability, classified under CWE-22, in Samsung Electronics MagicINFO 9 Server versions less than 21.1080.0. The flaw enables attackers to upload a web shell to the web server due to inadequate path validation.
The vulnerability carries 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 it is exploitable remotely over the network by unauthenticated attackers with low attack complexity and no user interaction. Exploitation allows attackers to upload a web shell, achieving high impacts on confidentiality, integrity, and availability, such as remote code execution on the server.
