MicroStation CONNECT Edition Update 15.2 (

The MicroStation product team is pleased to announce the availability of MicroStation CONNECT Edition Update 15.2 ( on Software Downloads and as a downloadable update from the CONNECTION Client. This MicroStation CONNECT Edition Update includes: 

  • New Collaborate Ribbon Tab consolidates the tools needed for working together with your Project Team under one convenient location in the User Interface.   
  • Attach iTwin – This new tool allows you to bring the data-rich iTwin from an iModel that has been synchronized to your Project Portal into your DGN file as a reference.  Use your Digital iTwin as a starting point or reference in your designs. 
  • The update resolves an Improper Input Validation vulnerability (CWE-20) where a DGN file could crafted to introduce data that is not expected by the application causing unpredictable or unwanted behavior at application startup. Bentley has not observed this vulnerability being actively exploited for malicious purposes but as it is theoretically possible to do so, Bentley strongly recommends treating this as a material update and deploying with priority to sensitive environments.    This change applies to an obsolete feature not generally used by modern MicroStation users. If you are unable to update your application to 15.2 at this time, the following patch is available to apply to older versions of MicroStation and MicroStation-based applications. This patch is applicable to MicroStation and MicroStation based applications V8i and Connect Edition.
