Security readout for executives and security teams
Plain-English summary
Bentley View 10.15.0.75 can be made to run attacker-controlled code if a user opens a malicious JT file or visits a malicious page. The risk is mainly to engineering workstations and document-review workflows, not exposed servers. No active exploitation is shown in the provided sources or KEV status.
Executive priority
Treat this as a high-priority workstation risk for engineering and design environments. It is not documented as actively exploited, but compromise could give an attacker code execution on systems that may access sensitive project files.
Technical view
CVE-2021-46625 is a CWE-415 double-free issue in Bentley View JT file handling. The flaw involves failing to validate an object before additional free operations. Successful exploitation requires user interaction and can execute code in the current process context. CVSS is 7.8 high with local attack vector and required user interaction.
Likely exposure
Organizations using Bentley View 10.15.0.75 to view JT or CAD-related files are the primary exposure. Risk increases where users receive external model files, supplier documents, or project files from untrusted sources.
Exploitation context
The provided record describes remote attacker delivery, but exploitation depends on a target opening a malicious file or visiting a malicious page. KEV is false, and the bundle does not provide evidence of active exploitation.
Researcher notes
Evidence supports a double-free in JT parsing with code execution in the current process. The bundle does not include patch version details, exploit maturity, or proof of exploitation. Avoid assuming affected versions beyond Bentley View 10.15.0.75.
Mitigation direction
- Identify and prioritize systems running Bentley View 10.15.0.75.
- Check Bentley BE-2021-0005 for vendor-approved updates or remediation.
- Restrict opening JT files from untrusted external sources.
- Apply endpoint controls for high-risk engineering workstations.
- Educate affected users about suspicious CAD/model file handling.
Validation and detection
- Inventory installed Bentley View versions across engineering endpoints.
- Confirm whether version 10.15.0.75 is present.
- Review file-association and email/web download controls for JT files.
- Check endpoint telemetry for unexpected Bentley View child processes.
- Track remediation status against Bentley advisory BE-2021-0005.

Double Free
Double Free represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
