CVE-2022-35906: An issue was discovered in Bentley MicroStation before 10.17.0.x and Bentley View before 10.17.0.x.

An issue was discovered in Bentley MicroStation before 10.17.0.x and Bentley View before 10.17.0.x. Using an affected version of MicroStation or MicroStation-based application to open a DGN file containing crafted data can force an out-of-bounds read. Exploitation of these vulnerabilities within the parsing of DGN files could enable an attacker to read information in the context of the current process.

Security readout for executives and security teams

Plain-English summary

This is a low-severity file-parsing issue in Bentley MicroStation and Bentley View. An attacker would need a user to open a specially crafted DGN file in an affected version. Successful exploitation could expose limited information from the running application process, not provide code execution or system takeover based on the supplied sources.

Executive priority

Handle through the normal vulnerability management cycle, with higher priority for design teams exchanging DGN files externally. Business urgency is limited by low CVSS impact and required user interaction, but patching reduces avoidable information exposure risk.

Technical view

Bentley MicroStation and Bentley View before 10.17.0.x can trigger an out-of-bounds read while parsing crafted DGN data. The CVSS 3.1 vector is local, low complexity, no privileges required, user interaction required, and low confidentiality impact only. Integrity and availability impacts are not identified in the source bundle.

Likely exposure

Exposure is most likely where engineering, design, or review teams use Bentley MicroStation, Bentley View, or MicroStation-based applications before 10.17.0.x and open DGN files received from external or untrusted sources.

Exploitation context

The supplied sources do not indicate active exploitation, and the CVE is not marked KEV. Exploitation depends on convincing a user to open a crafted DGN file in an affected application. Evidence provided supports information disclosure in the current process only.

Researcher notes

Key constraints are AV:L, UI:R, C:L, I:N, and A:N. The provided record does not list CWE data or public exploit evidence. Validation should focus on product versioning, DGN ingestion paths, and whether MicroStation-based applications inherit the affected parser.

Mitigation direction

  • Upgrade affected Bentley MicroStation and Bentley View installations to 10.17.0.x or later.
  • Review Bentley advisory BE-2022-0011 for product-specific guidance.
  • Limit opening DGN files from untrusted or unexpected sources.
  • Apply file-handling controls for externally supplied engineering files.
  • Prioritize users who routinely receive third-party DGN files.

Validation and detection

  • Inventory Bentley MicroStation and Bentley View versions across workstations.
  • Confirm no installed affected product remains below 10.17.0.x.
  • Identify teams that open external DGN files.
  • Check software deployment records for completed Bentley updates.
  • Review mail, portal, or project workflows that deliver DGN files.
