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 Bentley MicroStation CONNECT 10.16.02.34. 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 DGN files. Crafted data in a DGN file can trigger a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-16468.

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 buffer overflow vulnerability exists in Bentley MicroStation CONNECT's DGN file parser. When parsing a maliciously crafted DGN file containing data that writes beyond the bounds of an allocated buffer, an attacker can achieve arbitrary code execution in the context of the current user process. User interaction is required (opening a malicious file).

MitigationDo not open untrusted or unverified DGN files. Apply the vendor patch when released. Implement file origin validation and consider sandboxing or restricted privileges for file parsing operations.

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. Verify if Bentley MicroStation or View is installed
    Check for the application in typical installation locations such as C:\Program Files\Bentley\MicroStation, or look for the program in Start Menu > Bentley. You can also check Add/Remove Programs for Bentley MicroStation or Bentley View.
    Affected if Either Bentley MicroStation or Bentley View is present on the system
  2. Identify the exact version of the installed product
    Right-click on the MicroStation or View executable (typically ms*.exe in the program folder), select Properties, and check the File Version field. Alternatively, open the application and go to Help > About to view the version information.
    Affected if The version displayed is below 10.16.03 (for example, 10.16.00, 10.15.x, or earlier)
  3. Confirm DGN file handling capability is present
    Verify the software can open or process DGN files by checking if DGN-related file associations exist (.dgn extension registered to the application) or by confirming the DGN import/ export tools are available within the software.
    Affected if The software can parse DGN files - no special configuration is required as the vulnerability exists in the core DGN parser component

You are affected if Bentley MicroStation or Bentley View is installed with a version number lower than 10.16.03 and the software can process DGN files.

Upgrade available Upgrade to 10.16.03 or later
Fixed in 10.16.03
Interim mitigation

Do not open untrusted or unverified DGN files. Apply the vendor patch when released. Implement file origin validation and consider sandboxing or restricted privileges for file parsing operations.

Recommended fix High confidence

10.16.03 or later

  1. 1. Check the current version of Bentley MicroStation or MicroStation View by opening the application and navigating to the About section
  2. 2. If the version is below 10.16.03, navigate to the official Bentley website or Bentley Communities portal to obtain the version 10.16.03 (or later) installer
  3. 3. Download the installer for MicroStation CONNECT or MicroStation View version 10.16.03 or later
  4. 4. Run the installer and follow the on-screen prompts to complete the upgrade
  5. 5. After installation, verify the version number shows 10.16.03 or higher to confirm the patch has been applied
  6. 6. Test that DGN file parsing works correctly with the updated version
