Delta Electronics DTN Soft Project File Parsing Deserialization of Untrusted Data Remote Code Execution

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

Delta Electronics DTN Soft contains a deserialization vulnerability when parsing project files. An attacker can craft a malicious project file that, when opened by a victim, deserializes untrusted data leading to arbitrary code execution on the targeted system.

MitigationRestrict access to DTN Soft and avoid opening project files from untrusted or unknown sources. If available, apply vendor-supplied patches and consider network segmentation for industrial control system environments.

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 DTN Soft installation
    Search the system for Delta Electronics DTN Soft - check Program Files directories, look for DTN Soft executables, or run 'Get-ItemProperty' for installed software listing Delta
    Affected if DTN Soft is present on the system
  2. Determine installed version
    Right-click the DTN Soft executable and view Properties > Details, or check the Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for Delta entries
    Affected if Version cannot be determined or falls within an unpatched release range
  3. Locate project files
    Search for file extensions associated with DTN Soft project files (common patterns include .dtn, .dtp, .prj, or files modified within the DTN Soft application data folder)
    Affected if Project files with DTN-related extensions exist on the system or in accessible directories
  4. Verify project file handling is enabled
    Check if the DTN Soft application has file association handlers registered for project file types, and whether the deserialization parser is functional (no disabled features preventing file loading)
    Affected if DTN Soft can open and parse project files through its normal interface
  5. Inspect application deserialization behavior
    Monitor DTN Soft process during project file loading using process monitoring tools - observe if the application performs deserialization of file contents without validation
    Affected if The application deserializes project file data automatically upon file opening

If Delta Electronics DTN Soft is installed and can open or parse project files, the environment is potentially affected by this deserialization vulnerability.

Mitigation

Restrict access to DTN Soft and avoid opening project files from untrusted or unknown sources. If available, apply vendor-supplied patches and consider network segmentation for industrial control system environments.
