CVE-2022-28641

Code execution via invalid IFC object use

Published Mar 29, 2023 · Updated Feb 18, 2025

Use-after-free in the IFC parser in Bentley Systems MicroStation CONNECT 10.16.02.34 allows remote attackers to execute arbitrary code. The parser performs operations on an IFC object without first validating that the object still exists, dereferencing freed memory. Exploitation requires a user to visit a malicious page or open a crafted IFC file, and code runs with the privileges of the current process.
