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 disclose sensitive information 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 3DS files. Crafted data in a 3DS file can trigger a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-16343.

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 an out-of-bounds read vulnerability in Bentley MicroStation CONNECT's 3DS file parser. A malicious 3DS file with crafted data can trigger a read past the end of an allocated buffer, allowing remote attackers to disclose sensitive information from memory. User interaction is required (opening the file), and this flaw can be chained with other vulnerabilities for arbitrary code execution.

MitigationApply the vendor patch from Bentley for MicroStation CONNECT. Until patched, instruct users to avoid opening 3DS files from untrusted 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 the installed Bentley product
    Check Programs and Features (Windows) or the application's About dialog for the product name - either MicroStation CONNECT or Bentley View
    Affected if The product is Bentley MicroStation CONNECT or Bentley View
  2. Determine the installed version number
    Open the application, go to Help > About Bentley [Product Name], or check the version in the application's main window. The version is typically displayed as 10.x.x.x
    Affected if The version number is lower than 10.16.03 (e.g., 10.16.00, 10.15.x, 10.14.x, etc.)
  3. Confirm 3DS file handling capability exists
    Verify the application can open or import 3DS files by checking File > Open or File > Import for .3ds file type support, or attempt to open a known 3DS file
    Affected if The 3DS file import/open functionality is present and accessible in the installed version
  4. Verify the vulnerability window
    Cross-reference the specific build number with Bentley's security advisory if available, noting that any version below 10.16.03 is considered vulnerable
    Affected if The installed version is 10.16.02, 10.16.01, 10.16.00, or any earlier minor version

You are affected if Bentley MicroStation CONNECT or Bentley View is installed with any version below 10.16.03 and the 3DS file import feature is available to users.
