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
This vulnerability allows remote attackers to execute arbitrary code on affected installations of KOYO Screen Creator 0.1.1.1. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of SCA2 files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-14868.

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

This is a stack-based buffer overflow vulnerability in KOYO Screen Creator 0.1.1.1's SCA2 file parser. The application fails to validate the length of user-supplied data before copying it to a fixed-length stack buffer, allowing arbitrary code execution in the context of the current process when a user opens a malicious SCA2 file.

MitigationAvoid opening untrusted SCA2 files from unknown or untrusted sources. Implement proper input validation and bounds checking in the SCA2 file parser to ensure data lengths are validated before copying to buffers.

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. Identify installed version of Jtekt Screen Creator Advance 2
    Open the application and navigate to Help > About, or check the program's properties in the Windows Explorer file details. Look for the exact version number displayed.
    Affected if The version listed is less than 0.1.1.4 or exactly 0.1.1.4
  2. Confirm the SCA2 file parser feature is present
    Verify the application installation includes the SCA2 file parsing capability. Check if the program can open or create .sca2 project files.
    Affected if The application has the ability to parse SCA2 files and the version is in the affected range
  3. Locate the application executable
    Find the main executable (typically named JtektScreenCreatorAdvance2.exe or similar) in the installation directory, commonly under C:\Program Files\KOYO or C:\Program Files\Jtekt.
    Affected if The executable exists and its version property shows an affected version number

A user is affected if Jtekt Screen Creator Advance 2 is installed with a version less than 0.1.1.4 or exactly 0.1.1.4, and the SCA2 file parser feature is available for processing project files.

dbcve · scoped
Upgrade available Upgrade to 0.1.1.4 or later
Fixed in 0.1.1.4
Interim mitigation

Avoid opening untrusted SCA2 files from unknown or untrusted sources. Implement proper input validation and bounds checking in the SCA2 file parser to ensure data lengths are validated before copying to buffers.

Recommended fix Moderate confidence

Screen Creator Advance 2 version > 0.1.1.4 (first stable release after 0.1.1.4)

  1. 1. Identify the currently installed version of KOYO Screen Creator Advance 2 by opening the application and checking About or Help menu
  2. 2. If the installed version is 0.1.1.4 or earlier, navigate to the official vendor website at www.koyoele.co.jp to obtain the latest version
  3. 3. Download the updated Screen Creator Advance 2 installer
  4. 4. Close the running application if currently open
  5. 5. Run the installer and follow the on-screen prompts to update the software
  6. 6. After installation completes, verify the new version by checking About/ Help to confirm the vulnerability is remediated
Caveat Minimal risk; as a minor version update within the same major release, backward compatibility with existing SCA2 project files is expected
