Name of the Vulnerable Software and Affected Versions Bentley MicroStation CONNECT version 10.16.0.80

Description This issue allows remote attackers to disclose sensitive information on affected installations. It requires user interaction, where the target must visit a malicious page or open a malicious file. The flaw exists within the parsing of DWG files due to the lack of proper validation of user-supplied data, resulting in a read past the end of an allocated buffer. An attacker can leverage this, potentially in conjunction with other issues, to execute arbitrary code in the context of the current process.

Recommendations For version 10.16.0.80, as a temporary workaround, consider restricting the parsing of DWG files or limiting user interaction with potentially malicious files until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
