Security readout for executives and security teams
Plain-English summary
CVE-2021-46627 affects Bentley View 10.15.0.75. A user who opens a malicious DXF file or visits a malicious page could allow code execution in the Bentley View process. This is high risk for organizations using Bentley View to inspect CAD files from external parties.
Executive priority
Treat this as a high-priority workstation exposure where CAD viewers handle external files. Prioritize engineering, design, facilities, and project teams that exchange DXF content with outside parties.
Technical view
The flaw is in DXF file parsing and is associated with CWE-416. The source describes missing validation of an object before operations are performed on it, enabling arbitrary code execution in the current process. Exploitation requires user interaction and is scored CVSS 7.8 high.
Likely exposure
Exposure is most likely on workstations where Bentley View 10.15.0.75 is installed and used to open DXF files, especially files received from customers, suppliers, project partners, email, or web downloads.
Exploitation context
The supplied sources do not show CISA KEV listing or active exploitation. Exploitation is not described as remote network exploitation; it requires a targeted user to open a malicious file or visit a malicious page.
Researcher notes
The record links this issue to ZDI-CAN-15457 and ZDI-22-214. The available description supports arbitrary code execution through crafted DXF parsing with user interaction. The supplied evidence does not include exploit-in-the-wild confirmation or detailed fixed-version text.
Mitigation direction
- Identify and prioritize Bentley View 10.15.0.75 installations.
- Check Bentley advisory BE-2021-0011 for vendor-approved fixes or updates.
- Restrict opening DXF files from untrusted sources until remediated.
- Use endpoint controls to quarantine suspicious CAD files and downloads.
- Run Bentley View with standard user privileges, not administrator rights.
Validation and detection
- Inventory endpoints for Bentley View version 10.15.0.75.
- Confirm whether affected users handle externally supplied DXF files.
- Review vendor advisory BE-2021-0011 for fixed-version status.
- Check file association policies for DXF handling on endpoints.
- Review endpoint telemetry for suspicious Bentley View crashes or child processes.
