CVE-2021-46647 – Bentley MicroStation CONNECT BMP File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-46647
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 BMP images. 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-2021-0002 https://www.zerodayinitiative.com/advisories/ZDI-22-234 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVE-2021-46569 – Bentley MicroStation CONNECT JT File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-46569
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-22-156 • CWE-787: Out-of-bounds Write •
CVE-2021-46571 – Bentley View JT File Parsing Use-After-Free Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-46571
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Bentley View 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 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-2021-0005 https://www.zerodayinitiative.com/advisories/ZDI-22-158 • CWE-416: Use After Free •
CVE-2021-46642 – Bentley View DGN File Parsing Out-Of-Bounds Read Information Disclosure Vulnerability
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 •
