CVSS: 7.8EPSS: 0%CPEs: 3EXPL: 0CVE-2021-46634 – Bentley MicroStation CONNECT JT File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-46634
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 JT files. Crafted data in a JT file can trigger a write past the end of an allocated 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-2021-0005 https://www.zerodayinitiative.com/advisories/ZDI-22-221 • CWE-787: Out-of-bounds Write •

CVSS: 7.8EPSS: 0%CPEs: 3EXPL: 0CVE-2021-46598 – Bentley MicroStation CONNECT JT File Parsing Memory Corruption Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-46598
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 JT files. The issue results from the lack of proper validation of user-supplied data, which can result in a memory corruption condition. 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-2021-0005 https://www.zerodayinitiative.com/advisories/ZDI-22-185 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
