CVE-2021-46620 – Bentley MicroStation CONNECT FBX File Parsing Out-Of-Bounds Read Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2021-46620
This vulnerability allows remote attackers to disclose sensitive information 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 FBX 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-2021-0012 https://www.zerodayinitiative.com/advisories/ZDI-22-207 • CWE-125: Out-of-bounds Read •
CVE-2021-46621 – Bentley MicroStation CONNECT JT File Parsing Double Free Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-46621
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 handling of JT files. The issue results from the lack of validating the existence of an object prior to performing further free operations on the object.
