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 IFC files. Crafted data in an IFC 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-16332.

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

A buffer overflow vulnerability exists in Bentley MicroStation CONNECT's IFC file parser. When parsing a specially crafted IFC file containing malformed data, the parser writes past the end of an allocated buffer, allowing an attacker to execute arbitrary code in the context of the current user process.

MitigationUsers should avoid opening IFC files from untrusted sources. Apply vendor-provided security patches for MicroStation CONNECT when available. Consider implementing additional file validation and sandboxing for IFC file processing.

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 if Bentley MicroStation CONNECT or Bentley View is installed
    Open Windows Control Panel > Programs and Features, or check for MicroStation.exe or BentleyView.exe in the installation directory (commonly C:\Program Files\Bentley\MicroStation or C:\Program Files\Bentley\View)
    Affected if Either product is installed and the version is below 10.16.03
  2. Determine the installed version number
    Right-click the executable (MicroStation.exe or BentleyView.exe), select Properties, then view the Details tab for Product Version. Alternatively, open the application and go to Help > About MicroStation or About Bentley View
    Affected if The reported version is lower than 10.16.03 (for example, 10.16.00, 10.15.x, or earlier)
  3. Verify IFC file handling capability is present
    Attempt to open an IFC file or check if IFC import/export options are available in the software (File > Import or File > Export menus). The IFC parser is bundled with the product.
    Affected if IFC file handling functionality exists in the installed software, which means the vulnerable parser code is present
  4. Assess exposure to untrusted IFC files
    Review workflows to determine if the software is used to open IFC files from external or untrusted sources, or if IFC files are received via email, downloads, or shared network locations
    Affected if Users routinely open IFC files from sources outside the organization or from untrusted internal sources

A user is affected if Bentley MicroStation CONNECT or Bentley View is installed with a version lower than 10.16.03 and the software has access to the IFC file parser, particularly if users open IFC files from untrusted sources.

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

Users should avoid opening IFC files from untrusted sources. Apply vendor-provided security patches for MicroStation CONNECT when available. Consider implementing additional file validation and sandboxing for IFC file processing.

Recommended fix High confidence

MicroStation 10.16.03 or View 10.16.03

  1. 1. Check current MicroStation or View version by opening the application and navigating to Help > About MicroStation or Help > About View
  2. 2. If version is below 10.16.03, download the update from the official Bentley website (www.bentley.com) or through the Bentley Communities portal
  3. 3. Close all Bentley applications before installing the update
  4. 4. Run the installer and follow the on-screen prompts to complete the installation
  5. 5. After installation, verify the version by checking Help > About to confirm version 10.16.03 or later is installed
Caveat Routine security update; verify that custom workspaces, templates, or IFC workflows function correctly after upgrading
