CVE-2025-54438
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Samsung Electronics MagicINFO 9 Server allows Upload a Web Shell to a Web Server.This issue affects MagicINFO 9 Server: less than 21.1080.0
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceMagicINFO 9 Server versions prior to 21.1080.0 contain a path traversal vulnerability in the file upload functionality that allows attackers to escape the intended upload directory and place arbitrary files, including web shells, onto the server. This enables remote code execution on the affected system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed MagicINFO 9 Server versionLocate the version information for Samsung MagicINFO 9 Server (typically found in the application UI, an about page, or server configuration files) and compare it to the affected range of versions prior to 21.1080.0Affected if The installed version is lower than 21.1080.0
-
Verify file upload functionality exposureDetermine whether the file upload endpoint is accessible on the MagicINFO 9 Server (commonly found at paths such as /upload, /file/upload, or similar upload-related endpoints)Affected if The file upload functionality is accessible without authentication or proper access controls
-
Check server network accessibilityAssess whether the MagicINFO 9 Server is directly accessible from untrusted networks (internet or unauthorized LAN segments)Affected if The server accepts unauthenticated connections from untrusted sources
-
Inspect web directories for unexpected filesExamine the web root and writable directories for unfamiliar scripts, especially those with extensions such as .jsp, .asp, .php, .exe, or .sh that may indicate web shells or malicious uploadsAffected if Unexpected executable or script files are found in web-accessible directories
You are affected if your MagicINFO 9 Server version is below 21.1080.0 and the file upload functionality is accessible to unauthenticated users.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped21.1080.0
Upgrade MagicINFO 9 Server to version 21.1080.0 or later to remediate the path traversal vulnerability. After upgrading, verify that file upload functionality restricts uploads to intended directories and does not permit executable file types.
MagicINFO 9 Server version 21.1080.0 or later
- 1. Identify the current MagicINFO 9 Server version by accessing the admin interface or checking system information
- 2. Download MagicINFO 9 Server version 21.1080.0 or later from the official Samsung download portal at security.samsungtv.com or the Samsung MagicINFO support site
- 3. Create a full backup of the current MagicINFO 9 Server installation including configuration files and database
- 4. Stop the MagicINFO 9 Server service before applying the upgrade
- 5. Apply the upgrade by running the installer for version 21.1080.0 or later
- 6. Start the MagicINFO 9 Server service after upgrade completion
- 7. Verify the installed version shows 21.1080.0 or later in the admin interface
- 8. Test that the path traversal vulnerability is remediated by verifying file upload restrictions are enforced
