Successful exploitation of these vulnerabilities may crash the device being accessed or allow remote arbitrary code execution.
The following versions of Bentley Systems MicroStation Connect, a software management platform, are affected:
ā¢ v10.17.0.209 and prior
The affected product is vulnerable to a stack-based buffer overflow when a malformed design (DGN) file is parsed. This may allow an attacker to execute arbitrary code.
CVE-2022-40201 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
The affected product is vulnerable to an out-of-bounds read when parsing DGN files, which may allow an attacker to crash the product, disclose sensitive information, or execute arbitrary code.
CVE-2022-41613 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
Michael Heinzl reported these vulnerabilities to CISA.
Bentley Systems has implemented multiple validation checks within the DGN platform when processing malformed DGNs. Bentley Systems recommends users update to the latest version of the MicroStation Connect:

CISA recommends users take the following measures to protect themselves from social engineering attacks:
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage at cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01BāTargeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
No known public exploits specifically target these vulnerabilities. These vulnerabilities are not exploitable remotely.
