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

Description This issue allows remote attackers to disclose sensitive information 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 DGN files, where crafted data can trigger a read past the end of an allocated buffer. This can be leveraged in conjunction with other issues to execute arbitrary code in the context of the current process.

Recommendations For version 10.16.02.34, as a temporary workaround, consider restricting the use of DGN file parsing until a patch is available. Avoid opening malicious files or visiting untrusted pages to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
