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 · unedited
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in Samsung Electronics MagicINFO 9 Server allows Code Injection.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 · moderate confidence

A path traversal vulnerability in Samsung MagicINFO 9 Server (versions prior to 21.1080.0) allows attackers to escape restricted directories and inject malicious code. The improper limitation of pathname to a restricted directory enables remote code execution with critical severity (CVSS 9.8), likely exploitable over network without authentication.

MitigationUpgrade MagicINFO 9 Server to version 21.1080.0 or later to remediate the path traversal vulnerability. If immediate upgrade is not feasible, implement strict file system access controls and network segmentation to limit exposure.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Samsung MagicINFO 9 Server installation
    Check for MagicINFO 9 Server in installed programs (Windows: Add/Remove Programs, Linux: package manager), or look for the service process named 'MagicINFO' or 'MagicINFO Server' running on the system.
    Affected if Samsung MagicINFO 9 Server is installed and running on the system.
  2. Identify installed MagicINFO version
    Locate the MagicINFO installation directory and check for a version file, or use the MagicINFO admin interface to view version information. Common paths include C:\Program Files\Samsung\MagicINFO\ or /opt/magicinfo/. The version is typically displayed in the application or in a version.txt/readme file.
    Affected if The installed version is any version prior to 21.1080.0.
  3. Verify file upload or content serving functionality
    Review MagicINFO configuration files (typically in config/ or settings/ directories within the installation folder) to confirm if file upload, media import, or web content serving features are enabled.
    Affected if File upload, media import, or web content serving features are enabled in MagicINFO configuration.
  4. Assess network accessibility of MagicINFO service
    Check if MagicINFO server ports (commonly 7001, 8080, or443 for web interface) are exposed to network accessible IPs. Use netstat or firewall rules to identify listening ports and their binding addresses.
    Affected if MagicINFO web interface or API ports are listening on a network-accessible IP address (not localhost only).

The system is affected if Samsung MagicINFO 9 Server version is installed and the version is lower than 21.1080.0, with the web interface accessible over the network.

Interim mitigation

Upgrade MagicINFO 9 Server to version 21.1080.0 or later to remediate the path traversal vulnerability. If immediate upgrade is not feasible, implement strict file system access controls and network segmentation to limit exposure.

Recommended fix Moderate confidence

MagicINFO 9 Server version 21.1080.0 or later

  1. Identify the current MagicINFO 9 Server version by accessing the server administration interface or checking system information
  2. Access the Samsung security updates portal at https://security.samsungtv.com/securityUpdates to obtain the official patch for version 21.1080.0 or later
  3. Download the official Samsung MagicINFO 9 Server security patch
  4. Before applying the patch, perform a complete backup of the MagicINFO 9 Server database, configuration files, and any custom content
  5. Apply the security patch or upgrade to version 21.1080.0 following Samsung's official installation documentation
  6. After upgrade, verify the server version displays 21.1080.0 or higher
  7. Test critical functionality including file upload, content scheduling, and remote management to ensure proper operation
  8. Review system logs to confirm no path traversal errors or security exceptions remain
Caveat Review Samsung release notes for version 21.1080.0 for any configuration changes or compatibility considerations with existing content or integrations
