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
In Delta Electronics Automation TPEditor version 1.89 or prior, parsing a malformed program file may cause heap-based buffer overflow vulnerability, which may allow 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 · high confidence

Delta Electronics Automation TPEditor versions 1.89 and prior contain a heap-based buffer overflow vulnerability in the program file parsing functionality. When the application parses a specially crafted malformed program file, it fails to properly validate buffer sizes, allowing an attacker to overflow heap memory and achieve remote code execution.

MitigationUpgrade TPEditor to a version newer than 1.89. Until a patch is available, restrict network access to systems running TPEditor and avoid opening program files from untrusted sources.

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. Locate TPEditor installation
    Search for TPEditor.exe in common installation directories such as C:\Program Files\Delta Electronics\ or C:\Program Files (x86)\Delta Electronics\, or use system search utilities to find the executable
    Affected if TPEditor.exe is found on the system
  2. Determine installed TPEditor version
    Right-click on TPEditor.exe, select Properties, and view the Details tab for version information, or right-click the executable in File Explorer and select Properties
    Affected if Version displayed is 1.89 or any version lower than 1.89
  3. Verify version via file properties
    Check the Product Version field in the executable properties dialog. Alternative: right-click the executable, select Properties, and examine the File version field under the Version tab
    Affected if Product version shows 1.89 or prior (for example, 1.88, 1.87, 1.0, etc.)

A user is affected if TPEditor version 1.89 or earlier is installed on their system, since the heap-based buffer overflow vulnerability exists in all versions up to and including 1.89 when parsing program files.

Upgrade available Upgrade to 1.89 or later
Fixed in 1.89
Interim mitigation

Upgrade TPEditor to a version newer than 1.89. Until a patch is available, restrict network access to systems running TPEditor and avoid opening program files from untrusted sources.

Recommended fix Moderate confidence

TPEditor 1.89 or later

  1. 1. Identify the current version of TPEditor installed by opening the application and checking About or Help > Version information
  2. 2. Download TPEditor version 1.89 or later from the official Delta Electronics website or authorized distribution channels
  3. 3. Close any running instances of TPEditor before proceeding with the upgrade
  4. 4. Run the TPEditor installer with appropriate administrative privileges
  5. 5. Follow the installation wizard prompts to complete the upgrade, ensuring to backup any existing project files as a precaution
  6. 6. After installation, verify the installed version by checking Help > About to confirm version 1.89 or later is now running
  7. 7. Test that legitimate program files open correctly in the updated version
