Security readout for executives and security teams
Plain-English summary
CVE-2022-35902 is a low-severity file parsing flaw in Bentley MicroStation and Bentley View before 10.17.0.x. A user must open a malicious OBJ file. Successful exploitation may expose limited information from the application process.
Executive priority
Treat as routine patching unless your business frequently exchanges OBJ files with external parties. The impact is limited confidentiality exposure, but CAD workstations often handle sensitive project data, so remediation should be tracked.
Technical view
Affected Bentley MicroStation, Bentley View, and MicroStation-based applications can trigger an out-of-bounds read while parsing crafted OBJ data. CVSS 3.1 is 3.3, with local attack vector, low complexity, no privileges required, user interaction required, and low confidentiality impact.
Likely exposure
Exposure is most likely in engineering, CAD, or design teams using pre-10.17.0.x Bentley MicroStation or Bentley View to open OBJ files from external or untrusted sources.
Exploitation context
The provided sources do not indicate active exploitation or CISA KEV listing. Exploitation requires convincing a user to open a crafted OBJ file in an affected Bentley product or MicroStation-based application.
Researcher notes
No CWE is listed in the provided bundle, and no affected CPEs are provided. The vulnerability is an OBJ parser out-of-bounds read with confidentiality-only impact. Evidence for exploitation in the wild is absent from the supplied sources.
Mitigation direction
- Upgrade Bentley MicroStation and Bentley View to 10.17.0.x or later.
- Check Bentley advisory BE-2022-0016 for product-specific guidance.
- Restrict opening OBJ files from untrusted sources until affected systems are updated.
- Route external OBJ files through established content-handling controls.
Validation and detection
- Inventory Bentley MicroStation and Bentley View versions across CAD workstations.
- Identify MicroStation-based applications that parse OBJ files.
- Confirm installed versions are 10.17.0.x or later.
- Review workflows where users receive OBJ files from third parties.
