CVE-2021-46605: Bentley MicroStation CONNECT BMP File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability
First published: Fri Feb 18 2022(Updated: )
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. Was ZDI-CAN-15399.
