CVSS: 7.8EPSS: 0%CPEs: 3EXPL: 0CVE-2021-46638 – Bentley MicroStation CONNECT DGN File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-46638
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Bentley MicroStation CONNECT 10.16.0.80. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of DGN files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. • https://www.bentley.com/en/common-vulnerability-exposure/BE-2021-0009 https://www.zerodayinitiative.com/advisories/ZDI-22-225 • CWE-121: Stack-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2021-46642
This vulnerability allows remote attackers to disclose sensitive information on affected installations of Bentley View 10.15.0.75. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of DGN files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. • https://www.bentley.com/en/common-vulnerability-exposure/BE-2021-0009 https://www.zerodayinitiative.com/advisories/ZDI-22-229 • CWE-125: Out-of-bounds Read •
