CVE-2021-34891 – Bentley View JT File Parsing Use-After-Free Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-34891
This vulnerability allows remote attackers to execute arbitrary code 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 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-21-1480 • CWE-416: Use After Free •
CVE-2021-34882 – Bentley View JP2 File Parsing Out-Of-Bounds Read Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2021-34882
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 JP2 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-2021-0008 https://www.zerodayinitiative.com/advisories/ZDI-21-1471 • CWE-125: Out-of-bounds Read •
CVE-2021-34928 – Bentley View JT File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-34928
This vulnerability allows remote attackers to execute arbitrary code 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 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-21-1516 • CWE-787: Out-of-bounds Write •

CVE-2021-34945 – Bentley View JT File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-34945
This vulnerability allows remote attackers to execute arbitrary code 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 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-21-1533 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
