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 10.16.02.034. 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 OBJ 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-16171.

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 stack-based buffer overflow vulnerability in Bentley MicroStation CONNECT allows remote attackers to execute arbitrary code via a malicious OBJ file. The flaw exists in OBJ file parsing where the application fails to validate the length of user-supplied data before copying it into a fixed-size stack buffer, leading to memory corruption and potential code execution in the context of the current process.

MitigationApply the vendor security patch for MicroStation CONNECT when available; avoid opening untrusted or unsolicited OBJ files from unknown 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. Identify installed Bentley product
    Open Bentley MicroStation CONNECT or Bentley View, then go to Help > About to view the exact version number displayed in the product information dialog
    Affected if version shown is below 10.16.03 (for example, 10.16.00, 10.15.x, or earlier)
  2. Confirm product name
    Note whether the installed product is MicroStation CONNECT or Bentley View, as both are affected
    Affected if the product is Bentley MicroStation CONNECT or Bentley View with version below 10.16.03
  3. Assess OBJ file usage
    Determine if the application is used to open or import OBJ format 3D model files, as this is the attack vector for the vulnerability
    Affected if users routinely open OBJ files from untrusted or unknown sources in the affected software version

You are affected if you have Bentley MicroStation CONNECT or Bentley View installed with a version number lower than 10.16.03 and you open OBJ files in that application.
