Name of the Vulnerable Software and Affected Versions Bentley MicroStation CONNECT version 10.16.02.34

Description This issue allows remote attackers to execute arbitrary code on affected installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the parsing of IFC files due to 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 to execute code in the context of the current process.

Recommendations For Bentley MicroStation CONNECT version 10.16.02.34, update to a version that addresses the issue with parsing IFC files to prevent stack-based buffer overflow and remote code execution. As a temporary workaround, consider restricting the opening of IFC files from untrusted sources to minimize the risk of exploitation.
