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 10.16.0.80. 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 DXF files. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-15407.

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

This is a missing validation vulnerability in Bentley MicroStation CONNECT's DXF file parser. The parser fails to validate the existence of an object before performing operations on it, leading to arbitrary code execution when a user opens a specially crafted malicious DXF file.

MitigationDo not open untrusted DXF files; apply vendor security patches when released. Restrict file import to trusted sources only.

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 Bentley product
    Check Programs and Features (Windows) or application list for Bentley MicroStation, MicroStation Connect, or Bentley View
    Affected if One of these three products is installed
  2. Determine installed version
    Open the Bentley product, go to Help > About, or check the program's file properties (right-click executable > Details) for the version number
    Affected if Version is MicroStation < 10.16.02, MicroStation Connect <= 10.16.0.80, or Bentley View < 10.16.02
  3. Confirm DXF file handling is available
    Open the product and attempt to use File > Open or File > Import to verify DXF file support is present (this is a built-in parser included with the product)
    Affected if DXF file handling capability exists (default enabled in affected versions)

You are affected if you have MicroStation, MicroStation Connect, or Bentley View installed with a version number below the fixed releases (10.16.02 for MicroStation and View, 10.16.0.80 for Connect).
