CVE-2021-46622: Bentley MicroStation CONNECT J2K File Parsing Out-Of-Bounds Read 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 J2K images. Crafted data in a J2K image 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-15416.
