CVE-2022-1229: BE-2022-0006 | Bentley Systems | Infrastructure Engineering Software Company
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Bentley MicroStation CONNECT 10.16.2.034. 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 IFC files. Crafted data in an IFC 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. Was ZDI-CAN-16581.

**Summary
**MicroStation and MicroStation-based applications may be affected by IFC file parsing vulnerabilities when opening maliciously crafted IFC files. Exploiting these vulnerabilities could lead to code execution.
**Details
**The following vulnerabilities related to this advisory were discovered by TrendMicro ZDI: ZDI-CAN-16332, ZDI-CAN-16367, ZDI-CAN-16368, ZDI-CAN-16369, ZDI-CAN-16379, ZDI-CAN-16390, ZDI-CAN-16392, ZDI-CAN-16446, ZDI-CAN-16570, ZDI-CAN-16573 and ZDI-CAN-16581. Using an affected version of MicroStation or MicroStation-based application to open a IFC file containing maliciously crafted data can force an out-of-bounds read or write, stack overflow or uninitialized variable vulnerabilities. Exploitation of these vulnerabilities within the parsing of IFC files could enable an attacker to execute arbitrary code in the context of the current process.
