CVE-2021-46575 – Bentley MicroStation CONNECT DGN File Parsing Use-After-Free Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-46575
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 validating the existence of an object prior to performing operations on the object. 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-2021-0004 https://www.zerodayinitiative.com/advisories/ZDI-22-162 • CWE-416: Use After Free •
CVE-2021-46576 – Bentley MicroStation CONNECT JT File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-46576
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-22-163 • CWE-787: Out-of-bounds Write •
CVE-2021-46577 – Bentley MicroStation CONNECT JT File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-46577
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 the length of user-supplied data prior to copying it to a heap-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-2021-0005 https://www.zerodayinitiative.com/advisories/ZDI-22-164 • CWE-122: Heap-based Buffer Overflow •
