Security readout for executives and security teams
Plain-English summary
CVE-2021-46624 affects Bentley View 10.15.0.75. A crafted DWG file or malicious page can make the application read memory it should not access, potentially exposing limited sensitive information. It requires user interaction and is not listed as actively exploited in KEV.
Executive priority
Treat this as a targeted endpoint risk for teams handling CAD files, not an enterprise-wide emergency. Prioritize inventory and vendor remediation where Bentley View 10.15.0.75 is used with external DWG content.
Technical view
The flaw is a CWE-125 out-of-bounds read in Bentley View's DWG parsing. Improper validation of user-supplied DWG data can read past an allocated buffer. The CVSS 3.0 score is 3.3, with local attack vector, required user interaction, and low confidentiality impact.
Likely exposure
Exposure is most likely on engineering, design, or review workstations running Bentley View 10.15.0.75 and opening DWG files from external or untrusted sources. This is not described as a remotely exposed service vulnerability.
Exploitation context
The provided sources do not show active exploitation, and CISA KEV status is false. Exploitation requires the target to visit a malicious page or open a malicious file. ZDI notes the flaw could be combined with other vulnerabilities for code execution.
Researcher notes
Evidence supports an out-of-bounds read in DWG parsing with limited confidentiality impact. Public details state possible chaining with other vulnerabilities, but the bundle does not provide exploit details, active exploitation evidence, or a specific fixed version.
Mitigation direction
- Check Bentley advisory BE-2021-0010 for vendor-recommended remediation.
- Apply any Bentley-provided update or workaround after validation.
- Restrict opening DWG files from untrusted sources.
- Prioritize controls for users who receive external design files.
Validation and detection
- Inventory endpoints for Bentley View 10.15.0.75.
- Confirm whether affected users handle external DWG files.
- Review security telemetry for suspicious DWG-related crashes or alerts.
- Verify remediation status against Bentley advisory BE-2021-0010.
