BE-2022-0018: XMT File Parsing Out-of-bounds and Stack Overflow vulnerabilities in MicroStation and MicroStation-based applications
Bentley ID: BE-2022-0018
CVE ID: CVE-2022-42901
CVSS v3.1: AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Publication date: 2022-10-12

MicroStation and MicroStation-based applications may be affected by out-of-bounds and stack overflow vulnerabilities when opening maliciously crafted XMT files. Exploiting these vulnerabilities could lead to information disclosure and code execution.
Using an affected version of MicroStation or MicroStation-based application to open a XMT file containing maliciously crafted data can force an out-of-bounds read or write and can force the execution of arbitrary code. Exploitation of these vulnerabilities within the parsing of XMT files could enable an attacker to execute arbitrary code in the context of the current process.
|Applications||Affected Versions||Mitigated Versions|
|MicroStation||10.17.0.* and prior versions||10.17.01.58* and more recent|
|Bentley View||10.17.0.* and prior versions||10.17.01.19 and more recent|
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 XMT files coming from trusted sources.
