Description

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. 

 

Affected Versions:


Applications Affected Versions Mitigated Versions
MicroStation 10.16.02.* and prior version 10.16.03.* and more recent
Bentley View 10.16.02.* and prior version 10.16.03.* and more recent

Recommended Mitigations

Bentley recommends updating to the latest versions of MicroStation and MicroStation-based applications. As a general best practice, it is also recommended to only open IFC files coming from trusted sources.


Acknowledgement

Thanks to Mat Powell and Anonymous of Trend Micro Zero Day Initiative for discovering these vulnerabilities.
