Security readout for executives and security teams
Plain-English summary
A user with Bentley View 10.15.0.75 could be tricked into opening a malicious file or page. The BMP image parser may read memory beyond its intended buffer, exposing limited sensitive data. Sources rate this low, but it could support a larger attack chain.
Executive priority
Treat as a low-priority remediation unless Bentley View is widely used with untrusted external files. Address through normal workstation patch and software inventory processes, with higher priority for engineering teams exposed to third-party files.
Technical view
CVE-2021-46628 is a CWE-125 out-of-bounds read in Bentley View 10.15.0.75 BMP parsing. CVSS 3.0 is 3.3 with local attack vector and required user interaction. ZDI states it may be chained with other vulnerabilities for code execution in the current process.
Likely exposure
Exposure is likely limited to workstations running Bentley View 10.15.0.75, especially where users open externally supplied design files, images, email attachments, or web-delivered content.
Exploitation context
The source bundle does not show known active exploitation, and CISA KEV is false. Exploitation requires user interaction: visiting a malicious page or opening a malicious file. The documented direct impact is limited information disclosure.
Researcher notes
Evidence supports a user-assisted out-of-bounds read in BMP parsing. The arbitrary code execution statement is conditional on chaining with other vulnerabilities; the bundle does not identify those vulnerabilities, exploit availability, or a specific fixed version.
Mitigation direction
- Inventory Bentley View installations and identify version 10.15.0.75.
- Check Bentley advisory BE-2021-0002 for vendor-approved updates or mitigations.
- Limit opening untrusted BMP images or files in affected Bentley View installations.
- Use email and web controls to reduce delivery of untrusted files.
- Prioritize remediation on engineering workstations handling external project files.
Validation and detection
- Confirm whether Bentley View 10.15.0.75 exists in software inventory.
- Review endpoint telemetry for Bentley View crashes tied to image or file parsing.
- Check whether users receive external files opened in Bentley View.
- Verify vendor guidance has been applied to affected systems.
- Document any compensating controls for systems awaiting vendor remediation.

Out-of-bounds Read
Out-of-bounds Read represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
