Vulnerability from cvelistv5 – Published: 2022-01-13 21:43 – Updated: 2024-08-04 00:26

Summary

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 3DS files. Crafted data in a 3DS file can trigger a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-14833.
